Abstract

The present invention relates to a biological insecticidal composition containing Metarhizin, which uses Metarhizin and Indoxacarb as main active ingredients, wherein the weight ratio of Metarhizin and Indoxacarb is 1:20 -10:1, the active ingredient in the pesticidal composition has obvious synergistic effect on a variety of crop pests within the above ratio range; the biological pesticidal composition of the present invention can be prepared into any one suitable for agricultural use Formulation of preparation, the form of preparation is preferably any one of emulsifiable concentrate, water dispersible granules, microemulsion, suspending agent, water emulsion, and microcapsule suspending agent; the insecticidal composition of the present invention is mainly used for the control of diamondback moth and beet night Moths, cabbage butterflies, cotton bollworms and other lepidopteran pests.

Description

technical field [0001] The invention belongs to the technical field of biological pesticides, and specifically relates to a biological insecticidal composition comprising metarhizalin and indoxacarb. The biological insecticidal composition is safe and efficient, and is widely used in the prevention and treatment of various crop pests. Background technique [0002] Diamondback moth is a major pest of cruciferous vegetables worldwide. For a long time, the control of diamondback moth has mainly relied on chemical pesticides. Due to the irrational use of a large number of insecticides, the diamondback moth has developed high resistance to almost all insecticides developed before the 1990s. Since the 1990s, foreign pesticide companies have developed several new insecticides that have special effects on diamondback moths, such as abamectin, fipronil, organophosphorus, etc., but these insecticides are expensive and greatly increase the control cost, and the single use of these in...
