Former Research Director, Rodale Institute
Duties: The Rodale Institute® centered on a 333 acre campus operates as a certified organic
production/research farm in Kutztown, Pennsylvania. Since 2002, I led the research and training efforts
through inspiring my staff and by building alliances and cooperative Institutional linkages including Land
Grant Universities, Federal and State Research programs, and other private and public interest groups. The
Rodale Institute outreaches practical information based on its long term scientific research to farmers who
are interested in organic and sustainable farming systems. The Farming Systems Trial® (FST) is the longest
on-going experiment that evaluates the effects of conventional and organic systems on soil health, plant
production, economics, energy requirements, water quality, and other areas.
We outreach our research information through field days, educational activities and publications based on
tour our famous Farming Systems Trial, now in its 28th year and The Compost Utilization Trial long term
experiment at the Institute. The Compost Utilization Trial focuses on the comparison of the use of organic
and inorganic inputs for managing plant nutrient needs. Results from these and other trials are outreached to
local, regional, and international audiences and generate information to allow agriculture strategies and
policies that favor improvement of natural resources while maintaining effective and productive agriculture.
1
The Rodale Institute conducts International Programs in developing countries in Africa, Latin America, and
Asia and outreaches it results through the website, www.rodaleinstitute.org.
Under my leadership, we have developed and applied interdisciplinary, interdepartmental, and interinstitutional approaches to our programs. A major grant from USDA-CSREES, Using Research, Education
and Extension to help Small Farmers in the Initiative for Future Agriculture and Food Systems provided the
testing ground for applying these concepts with great success. In that grant, The Rodale Institute,
Pennsylvania State, Maryland, and Rutgers Cooperative Extension Services as well as Pennsylvania
Association for Sustainable Agriculture and Pennsylvania Certified Organic collaborators showed a 33.4%
annual increase in certified organic acres in the 3 state region of Pennsylvania, New Jersey, and Maryland
compared to 10.1% annual increase nationally.

Duties


Characterized bacterial wilt of ginger by Ralstonia solanacearum
Developed and verified control methods to mitigate agricultural losses
Major Accomplishments

Formed a coalition including members of the ginger industry, extension specialists, and researchers
from the USDA and University of Hawaii systems to combine resources to resolve the problem of
ginger bacterial wilt losses.

Used tissue culture plus controlled environment to create a clean culture system producing
improved seed-piece health and reducing bacterial wilt transmissions from infected seed-pieces.
The system was verified and tested under humid and semi-humid environment sites in Hawaii with
participation of USDA and University of Hawaii researchers.

System has been successfully used in several temperate greenhouse operations in Pennsylvania,
Virginia and North Carolina.

Demonstrated the hormonal control of ginger sprouting showing ethylene accelerated and
increased sprouting of ginger seed-pieces compared to non-treated and heat-treated ones. Tissue
culture plants were shown superior to conventional seed-pieces for the speed and extent of early
sprouting.

Analyzed ginger production returns, and acreage trends since 1952.
Showed how these statewide statistics quantify loss from the 1993-1994 epidemic resulted in 45%
overall yield losses and a reduction of acreage of over 30% in the following season 1994-1995.
2

Employed polyphasic testing (PCR, ELISA, and multiple strip tests) to identify and assay bacteria
from ginger rhizomes. Enterobacter cloacae was found widespread on ginger rhizomes for the first
time. This bacteria overgrew Ralstonia solanacearum cultures. Having many cultural and
physiological reactions in common with Rs, E. cloacae resulted problematic to Rs isolation,
purification and maintenance. Enterobacter cloacae grew more than six times faster than Ralstonia
solanacearum in culture. In addition its multiple antibiotic resistances makes conventional
selective isolations difficult.

Meta-analyzed over 350 articles on ginger horticultural and bacterial wilt.


Developed and tested new approaches for ginger bacterial wilt control including novel temperature
therapies, using bioassay for identifying field plant risks, use of systemic acquired resistance
mechanisms, integration of techniques to obtain adequate control methodology, and the role of
calcium in disease suppression.

Duties

Discovered the etiology of major diseases of economically important tropical plant species.

Conducted research to quantify disease losses, the way pathogens spread in host populations, the
nature of host genotypic resistance and tolerance reactions, the variability of the pathogen
populations, mechanisms of control, environmental factors associated with their prevalence and
severity, and interaction with other organisms.

Served as certifying Plant Pathologist in relations to Restricted Germplasm Grow outs in St. Croix
Virgin Islands to prevent major Old World exotic seed borne sorghum diseases from being
accidentally established in the New World by introduced germplasm.
Major Accomplishments
Papaya Pathology

We were able to culture the black rust or black spot pathogen (Asperisporium caricae Maubl.).
The fungus was the primary invader of succession of organisms leading to fruit decay. Black rust
ruptures the cuticle and grew intercellularly on the surface between the cuticle and the epidermis.
These furrowing are seen as star shaped lesions. The action of pathogen cytokinins lead to
formation of raised pustules and lead to the formation of green islands around lesions in maturing
fruits. Scars and pustules are subsequently colonized by brown spot (Colletotrichum
gloeopsorioides Penz.) and finally by soft rot Phomopsis caricae. Demonstrated biological
succession and allows better understanding the whole post harvest product deterioration syndrome
that starts in the field and continues to market and beyond. On papaya (Carica papaya L.) black
rust pustules are colonized by a grayish white hyperparasite identified as Hansfordia pulvinata that
attack a range of dematiaceous hyphomycetes leading to their discoloration and decline.

Novel papaya post harvest treatments were developed. The use of ultrasonic baths stimulated
lactifer latex release. The latex then covered the fruit. Latex covering was superior to
thiabendazole fungicide treatments in preventing fruit deterioration. The soaking of fruits in
calcium chloride solutions was found equal to thiabendazole standard treatment. Heat treatments
were found to promote fruit problems in decay and deterioration.
8

Mechanical damage related to improper fruit handling was identified as the most severe limitation
to achieving high quality fruit in the marketplace. Careful harvest and field packing effectively
eliminated most of this problem.

Heterosis of papaya was demonstrated and measured. Two major positive heterotic pattern was
identified and one negative one. Cariflora and PR 6-65 showed high parent heterosis when each
was crossed to Sunrise Solo. Criolla showed low parent heterosis being inferior the worst parent in
yield and quality parameters when crossed with Sunrise Solo.

Papaya germplasm was collected and tested for horticultural and disease reactions. The dioecious
papayas Cariflora and Washington had the highest tolerance levels to PRSV in Puerto Rico.
Germplasm was distributed throughout the Caribbean Basin and some were included in USDA
national papaya collection in Hawaii.

A recurrent selection program was developed to improve the disease reactions and horticultural
properties of Cariflora to Papaya Ringspot Virus PRSV tolerant source populations. Cariflora is
deficient in shape and texture properties being too soft and round for market preferences. We
identified elongate fruit types within the Cariflora populations than also had firmness. Among this
population random mating was initiated. Seedlings were inoculated with PRSV and the best 20% of
the reactions were transplanted into the field. After 3 generations of the procedure the inoculated
selections could produce 100 pounds of fruit after being inoculated in 3-leaf stage with virulent
local isolates.

An extension program in El Salvador led to the first successful Solo export papaya production in
that country. In that country, collected papaya germplasm collection was grown at sea level and
400 and 700 meter altitudes. At high elevation there was notable increases in hermaphroditism in
the accessions. Maradol selections from the collection had a high appreciation in the national
market and served as the source of that variety in that nation.

We found that anthracnose caused by Colletotrichum gloeosporioides Penz. was the major disease
limitation of water yam Dioscorea alata. The development of anthracnose epidemics was assayed
and resistant sources identified along with horticultural potentials.

The horticultural and disease potentials of other potentially commercial yam species such as
Dioscorea rotundata African White Yam, Dioscorea esculentum Chinese Yam, and new world
yam Dioscorea trifida were assayed and defined.

Cocoyam Xanthosoma sagittfolium was found to mostly limited by dry root rot. Fusarium solani
was the principle pathogen associated with condition. Rhizoctonia solani, Fusarium oxysporum,
and Pythium species were inoculated alone and in mixtures. Only Fusarium solani re-created the
dry root symptoms.

Tetraploid and Pentaploid accessions of cocoyams did not show high susceptibility to the dry root
rot disease but did not produce cormels either. Tetraploidy was induced in vitro to assess its
implications.

The flowering was induced with hormone treatments and crossing of diploid cocoyam plants was
achieved and used to develop increased genetic recombination and phenotypic variation in
cocoyam germplasm resources. Seed viability was also assessed from crosses.

Worked on post-harvest evaluation of cassava deterioration and the role of fungicides in its
amelioration.
9

Demonstrated the relationships of sorghum rust Puccinia purpurea severity to seed yield and
quality losses in sorghum using variable genotypic responses from immunity to very susceptible
and intermediates and using fungicidal control regimes to develop a broad range of rust epidemics.

Demonstrated the modifying relationship of environmental conditions to sorghum rust losses.
These losses are greater in semi-arid conditions than under sub-humid conditions with the same
rusting ratings.

Used genetic male sterility, ms3 gene in TP24 source population, to develop randomly mated
populations that were recurrently selected from rust resistance and agronomic traits. Multiple
culling levels were developed to give continual improved responses in each selection and
recombination generation. This source population was released and offers a bank of resistance
genes for sorghum rust pathogen resistance in improved genetic backgrounds.

Rust pustules hyperparasites were identified and studied. A succession of fungi was found on
sorghum rust pustule. Eudarluca filium, Verticillium lecanii, and Coniothyrium species were found
as rust hyperparasites.

Described Coniothyrium leaf spot of sorghum for the first time.

Identified the genotype, fungicide, and delayed harvest responses of sorghum to grain molds under
humid tropical conditions.

Found the relationship between grain filling and seed quality is an inverse one.

Identified major pathogens affecting the sorghum grain in Puerto Rico.

Defined the chemical control programs that promoted superior seed quality of sorghum in
susceptible varieties under severe humidity and high temperature environments.

Used toothpick inoculations with Fusarium moniliforme stalk rot pathogen to define disease
reactions. Developed a pink stalk rot resistant source population using random intermatings of
resistant sources out crossing under the influence of ms3 from the TP24 population. Interacted
with researchers in Georgia, Mexico, Puerto Rico, and Texas on this project.

Identified and described leaf blight Exserohilum turcicum resistant sources and the temperature
and seasonal nature of the disease in Puerto Rico. Determined the reactions of F1 hybrids using
identified leaf blight sources. Used TP24 populations and ms3 gene to develop randomly mated
populations that had improved blight resistance.

Participated in the New World effort to identify horizontal resistance to sorghum anthracnose.
Helped characterize the sorghum anthracnose races, their distributions, and the role of seed
transmission in disease development and movement.

Identified the race of sorghum downy mildew Pseudoperonspora maydis present in Southwest
Puerto Rico and the nature of this occurrence and severity.

Discovered the top and stalk rot bacteria on sorghum in Puerto Rico. The development of Erwinia
chrysanthemi Burkholder (McFadden & Dimock) was associated with use of silicone-based
surfactants in spray programs.

Crossed wild sorghum species into Sorghum bicolor (L.) Moench. using genetic male sterility
mechanisms. Sorghum proquinium and S. verticilliflorum were sources of improved rooting under
adverse soil conditions and increased drought tolerance and fertilizer use efficiency, and were
10
notable for less attack from insect pests. The recombined populations were re-domesticated by
recurrent recombination and selection for 5 generations.

Determined the factors related to scion dieback in graft-propagated cacao (Theobromae cacao L.)
and their control in Puerto Rico.

Identified Septoria pasiflorae leaf blight as the most limiting disease for passion fruit in Puerto
Rico. Developed a disease severity scale for assessing the problem and assessed germplasm
collections under several environments.

Worked on the resistance to early blight in tomato and its transfer from wild species into
domesticated species of tomato.

Worked in cooperation with USDA barley workers from Fargo North Dakota to speed the
identification and incorporation of new stem rust resistance to alleviate rust losses from a
breakdown in single gene resistance.

Identified southern blight on barley for the first time in the crop.

Worked with corn Zea mays L. project developing populations of field and sweet corn that are
adapted to the tropics and tolerant to major endemic diseases and pests and have improved
agronomic or horticultural characters. Populations improved included Sure Sweet Corn and Diente
de Caballo and Mayorbela field corn with introgression of Ohio populations 8 and 9.

Encouraged and aided the establishment of major seed industry players in the efforts to initiate and
sustain research and production facilities in Puerto Rico. Presented keynote address to American
Seed Association on this topic.
