Neem extract formulations to control Diabrotica speciosa (Coleoptera: Chrysomelidae) larvae in maize
Revista Colombiana de Entomología
Diabrotica speciosa larvae have been considered to be one of the major subterranean pests of several crops, and its most susceptible host is maize (Zea mays). This study aimed to evaluate the effects of oil-formulated neem extract and lignin-microencapsulated neem extract for D. speciosa larvae control. Effects of applications of neem formulations on the growth of maize plants were also assessed. In the first assay, 0.25, 0.5, 1.0, 2.0, and 4.0 mL of oil-formulated neem extract were applied perdoi:10.25100/socolen.v43i2.5949 fatcat:oqze2rmcmvcibaaxtwydxxgdey
