ECO-BIOLOGICAL CONTROL OF CALLOSOBRUCHUS ANALIS F. USING MORINDA CITRIFOLIA LEAF POWDER AND ITS EFFECTS ON SEED VIABILITY OF DETAM-1 BLACK SOYBEANS

Abstract

Background. One component of post-harvest management that aims to produce more competitive products is seed storage. Maintaining the viability of seeds for an extended period as planting material from one season to the next is the primary goal of seed storage

Aims. This article aims to study and determine the effectiveness of noni leaf powder on the development of the insect Callosobruchus analis F. (Coleoptera: Bruchidae) and the quality of black soybean seeds of the Detam-1 variety, as well as to obtain one of the doses of noni leaf powder that is effective in suppressing insect pests C. analyst F. and able to maintain the quality of black soybean seeds of the Detam-1 variety.

Methods.  The experiment, conducted using the experimental method, was carried out at the Laboratory of the Faculty of Agriculture, Winaya Mukti University, Tanjungsari, Sumedang, from April 2024 to June 2024. The environmental design employed was a Completely Randomized Design (CRD) with six treatments and four replications. The dosage treatment of noni leaf powder/100 g black soybeans is: A = 0.0 g, B = 2.5 g, C = 5.0 g, D = 7.5 g, E = 10.0 g, F = 12.5 g. Each treatment consists of two jars, resulting in a total of 48 jars.

Conclusion.  The results showed that a dose of noni leaf powder of 7.5 g was effective in increasing mortality, reducing the Number of eggs, larvae, and imago that appeared, and could maintain the quality of black soybean seeds in storage.
