Abstract
ABSTRACT
The development of red chili productivity is always greater than the productivity of cayenne pepper. The average annual productivity growth of the two commodities is 4% and 8.83%, respectively. The movement of chili productivity from 2010-2011 moved quickly, but in 2012 to 2016 it began to decline. One of the factors of decreased production due to Plant Pest Organisms (OPT) in chili is very diverse, especially thrips, mites, fruit caterpillars and fusarium wilt disease, viruses. Losses due to OPT This virus is very difficult to control and so far control has been carried out using chemicals. To increase consumer awareness of food safety and environmental conservation, one of the efforts to implement healthy nurseries can be done by increasing plant resistance. This study aims to determine the potential biological resources in the form of biological agents in the form of leaf extracts of pagoda flower and leaf extract of spine spinach that can increase plant resistance and suppress the development of pests in chili. Leaf extract of pagoda flower and leaf extract of spine spinach were sprayed when the chili plants were planted in the nursery. This research was conducted in Bocek village, Karangploso sub-district, Malang Regency from April to August 2019. The study used a Randomized Block Design (RAK) with 5 treatment combinations, namely leaf extract of pagoda flower (P1 Pagoda), leaf extract of spine spinach (P1 spinach), Poor farmers (P2), Blitar farmers (P3), control (P4) and each treatment plot consisted of 5 replications.
The results showed that immunization using leaf extract of spine spinach was effective in controlling important pests on red chili plants such as Mites (P.latus) with an efficacy level (90.32%), Thrips (92.51%), and H. armigera ( 45.16%), .For the disease is also effective using spinach leaf extract in controlling it with a virus efficacy level of 89.09% and fusarium wilt of 89.05%. The using leaf extract of spine spinach is a
