Effects Of Induced Plant Resistance And Potassium Fertilization Rates On Soybean Looper (Chrysodeixis Includens) Development In Soybean, Xuan Chen
LSU Master's Theses
Soybean looper, Chrysodeixis includens (Walker), is one of the most destructive pests of soybean in the southern U.S. It is highly resistant to most insecticides. Induced host plant resistance and cultural control are sought as alternative control tactics. In this study, effects of induced resistance by exogenous application of elicitors were estimated on soybean looper development in soybean. Three different known elicitors of SAR (systemic acquired resistance), Actigard 50WG (acibenzolar-S-methyl), Regalia (extract of Reynoutria sachalinensis) and methyl jasmonate (MeJA), were applied to soybean plants at R2 and R5 stages to determine if these chemicals could induce plant resistance and lower …
