Abstract
Numerous chemical insecticides have been used in order to control pests, which damage for agriculture. While chemical insecticides have knock down effect to the insect pests, they are too expensive in the developing countries and harmful to both human and the environment. One of the most important global problems is protecting crops from insect. For the control insects, synthetic chemical are continuously used. The implementation of integrated pest management aims to suppress adverse effects of the use of synthetic pesticides, plant pest immunity, prevent resurgence, and utilize as much as possible the ability of nature with using environmentally friendly microbio insecticide. Green mustard is a plant widely cultivated farmers in Indonesia, but green mustard plants also contain vitamins and nutrient that are important for health, because of the many cases of low productivity, one pests of caterpillars of causing farmers to suffer losses and the impact on the use of chemical insecticides by semi subsistence for control of caterpillar pests. To cope with the excessive use of chemical insecticides, the uses of microbio insecticide are more environmentally friendly can be applied. This study aimed to determine the mortality of insects, the rapid of time to control caterpillar pests at green mustard plants and to determine the concentration of B. thuringiensis the most effective way to control caterpillar pests on green mustard. In this result of study that it was found that the application of the most influence very real to the intensity of death caterpillar green mustard plants is K1 (Turex WP) with a concentration of 1g per liter. The best concentration and able to kill the caterpillars (Plutella xylostella) amounted to 71.00% within one day of observation after being treated.
