Abstract
Indonesia is the second largest exporter of peanuts to Europe. One of the export requirements is that exported peanuts do not contain pests and high levels of pesticides. Aphis craccivora Koch. is the main pest in peanuts and control generally uses pesticides which cause high pesticide levels. The aim of this research is to determine the application technique for biopesticides containing Streptomyces sp. and Trichoderma sp. as an enthomopathogen and chitosan which are able to control the population of the pest Aphis craccivora and the intensity of plant damage. The research was conducted and designed using factorial RAL where the first factor are application time before pest investment and after investment, factor 2 was chitosan concentration of 0,6%, 0,9%, and 1,2% in sugar potato extract solution (EKG). Each treatment combination was repeated 4 times. The results obtained were that the pre-investment application technique with a chitosan concentration of 1,2% was more capable of reducing the mortality of the pest A. craccivora by up to 70% and the application of biocide before investment with a concentration of 1,2% had a lower level of damage, namely 38,25%. Keywords: enthomopathogen, concentrations, chitinase, pre-investment, mortality.
