Abstract

The invention discloses a maize Athetis lepigone insecticide. The maize Athetis lepigone insecticide is prepared by using the following components in parts by weight: 1 part of emamectin benzoate, 1-5 parts of high effect cypermethrin, 2-6 parts of chlorpyrifos, 1-7 parts of indoxacarb, 3-7 parts of isofenphos-methyl, 18-26 parts of Chinese thorowax root, 25-35 parts of Radix codonopsis and 0.1-0.5 part of sodium carboxymethylcellulose. Compared with the prior art, the maize Athetis lepigone insecticide disclosed by the invention has the advantages that the efficacy is outstanding, the efficacy lasting period is long, the use time of the insecticide can be reduced, the raw materials are saved and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a pest killer, in particular to a pest killer specially used for cotton. Background technique [0002] Noctuid moth belongs to Lepidoptera Noctuidae, which is a new pest in my country's summer corn area, and it is often mistaken for cutworms in various places. With the growth of larval age, the pest will continue to increase its food intake, and the scope of occurrence will further expand. If it cannot be controlled in time, it will seriously threaten corn production. The corn field is heavy, and the larvae mainly hide under the broken wheat straw around the corn seedlings or harm the corn seedlings in the 2-5 cm topsoil layer. Generally, there are 1-2 insects per plant, and as many as 10-20 heads. In the field of corn seedlings at the 3-5 leaf stage, the larvae mainly bite the base of the corn stem, forming a 3-4 mm round or oval hole, cutting off the nutrient delivery, causing the aboveground corn heart leaves to wilt and di...
