Biopesticide Made from Rice Straw

Abstract

Rice straw is found abundantly in rice fields because the average straw produced from rice field area is 1.4 times the amount of its harvest. If the straw is composted, the yield of compost is 60%. This compost was made as a biopestisida after added with bacterium Pseudomonas putida H10. Beside of this, it also acted as biofertilizer because it was rich in nutrient content. When rice crops were sprayed three times with this biopesticide, the plants were resistance to rice blast and neck rot disease (Piricularia oryzae) and brown planthopper that attacked the area at that time, and increased the growth. This was indicated by the more number of tillers, more greener leaves, panicles were grown earlier, so that were harvested five days earlier than that plants not sprayed wih biopesticide. This biopestiside was also tested on tomato plants in order to control Fusarium wilt disease. It was sprayed in the earlier growth, the flowering and fruiting periods. It was turn out that this tomatoes were resistance to Fusarium wilt, thrips and leaf-eating pheasants (Spodoptera litura), also growing much better and more dense fruits.
