Abstract

A screening program was developed to detect chemicals without acute toxicity that could protect seedling corn from injuiy by southern corn rootworm (SCR), Diabrotica undecimpunctata howardi Barber. Crude plant extracts, purified secondary plant compounds and agricultural fungicides were screened in a no-choice laboratory bioassay using germinating corn seeds in soil. Promising candidates were further tested in a greenhouse assay. Chemicals were evaluated on the ability to reduce the number of plants damaged and the severity of SCR feeding. A seed treatment fungicide, thiram, energed as the most effective compound in these tests. The term phyto-protectant is used to describe substances which prevent or reduce the severity of insect damage to plants without regard to their specific mode of action. The usefulness and limitations of this screening program and terminology are discussed as well as implications for futher screening of phyto-protectants.
