Evaluation of kaolin-based particle film coatings on insect and disease suppression in apples

The Organic Farming Research Foundation of Santa Cruz, CA generously provided a grant of $3,479 in 1999 to initiate this study at the Southwest Research Center, Mt. Vernon, MO. The 2000 growing season was completed September 28, 2000, and I am pleased to submit this final summary of our results. A proposal for the funding of the second year's research has been submitted to OFRF. The particle film technology tested in this study appears to offer tremendous potential in safely suppressing both insects and disease in Midwestern apple production.

Organic Management of Garden Symphylans (Scutigerella immaculata) in Annual Cropping Systems

The garden symphylan is an increasingly common problem on organic farms. Symphylans have a diverse diet, feeding on decaying organic matter and on the roots of a very wide range of crops and other plants, including many weeds. Heavy symphylan populations can severely stunt, and even kill, most annual

Deploying microbes as a seed treatment for protection against soil-borne plant pathogens

Plant diseases, especially those caused by soil-borne seed infecting pathogens, pose a serious threat to the production of both greenhouse and field crops. Conventional farming operations often use fumigants and chemical seed treatments, which can be harmful to human health and the environment, for controlling seed and seedling pathogens.

Can Organic Garlic Seed Stock Be Created Disease-free from the Production of Garlic Bulbils?

Can Organic Garlic Seed Stock Be Created Disease-Free From the Production of Garlic Bulbils?

Serious diseases of garlic have been imported from foreign sources and are now widespread within the US and Canada. Stem and Bulb Nematode (Ditylenchus dipsaci) in garlic seed (vegetative reproduction) will infest the soil and is impossible to eradicate using organic approved methods. It is a threat to other crops, including onions, potatoes, alfalfa, and strawberries. Infested land is substantially reduced in value, as the nematode may be transferred on equipment.
