Abstract

ABSTRACT Abdul Rahmad (154110215), research entitled Influence Spraying Tuba Root Vegetable Pesticides and Rojokoyo Biopesticides Against Onion Plant Pest Attack (Allium ascalonicum L.). Below guidance of Dr. Ir. T. H. Edy Sabli, M.Sc. This research has been carried out in the experimental garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru, during 3 months from September to November 2019. Research objectives is to find out the Interaction and Main Effects of spraying pesticides plant-based tubal roots and biopesticides against pest attacks onion plants. The design used in the study was Random Design Complete Factorial consisting of two factors. The first factor is spraying tubal root vegetable pesticides (P) at a dose of 0, 5, 10, 15 ml / l water. While the second factor is rojokoyo biopesticides (B) with doses of 0, 5, 10, 15 ml / l of water. The parameter to be observed is leaf fly fly attack (HSP), attack armyworm (hsp), attack of caterpillar leeks (hsp), number of tubers good clump (tuber), the number of clump tubers damaged by the attack uret (tuber), good dry weight of tuber perump (tuber), dry weight of tuber per broken clump (tuber). The latest observational data were analyzed statistic and continued with further testing of BNJ at the 5% level. The results showed that the interaction was spraying tuba root vegetable pesticides and rojokoyo biopesticides have real effects against leaf fly borers, grayak caterpillars, leaf caterpillars onions, good amount of tuber per clump, number of tubers per clump broken, good dry bulbs per clump, good dry bulbs per clump the damaged one. The best treatment is in the combination of plant-based pesticides tuba root 10 ml / l water and 10 ml / lair biopesticide (P2B2). Main influence spraying of tuba root plant-based pesticides is evident against all parameters observation with the best treatment of 10 ml / l of water (P2). Main influence spraying real rojokoyo biopesticides against all observed parameters with the best treatment of 10 ml / l of water (B2).
