Problems solved by technology

[0003] Pesticide powder is mostly used in the prior art, and the most effective method at present is to adopt the hanging bag method, but there are still certain problems in the hanging bag method, such as the recycling problem of the hanging bag material, and because the coconut heart leaf beetle is not in the egg and pupa stages. Feed directly, resulting in poor killing effect on eggs and pupae

Abstract

The invention relates to the technical field of pesticides, in particular to a brontispa longissima control pesticidal tablet. The brontispa longissima control pesticidal tablet mainly comprises the following components: trichlorfon, acetamiprid, toosendanin, phospholipid oil, water lily, hypnum plumaeforme, morus wittiorum, diethylene glycol, sodium bisulfite, sodium p-toluenesulfonate, silica gel, sodium carboxymethyl starch, polyethylene glycol and lime powder. The brontispa longissima control pesticidal tablet kills brontispa longissima in a form of a pesticidal tablet, so that pollution to the environment during application in forms of spraying and the like is avoided; through reasonable compatibility and a reasonable preparation process, the components generate a synergistic effect to achieve omnibearing killing from eggs to adults; after application of the brontispa longissima control pesticidal tablet, the survival rate of the eggs is 0%, the survival rate of pupae is 0-1%, the survival rate of larvae is 0-1% and the survival rate of the adults is 0-2%; the brontispa longissima control pesticidal tablet has a significant effect of controlling the brontispa longissima.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a tablet of pesticides for preventing and controlling cocoa beetle and a preparation method thereof. Background technique [0002] Coconut heart beetle, also known as red chest leaf beetle, coconut flat beetle, coconut palm beetle, coconut bristle leaf beetle, is a serious dangerous alien pest, and it is an international second-class plant quarantine object that is prohibited from entering the country. , coconut-based palm palm plants, ranked third in the latest list of 19 kinds of forestry quarantine pests released by the State Forestry Administration. Coconut leaf beetle has the characteristics of fast reproduction, strong destructiveness and difficult control. [0003] Pesticide powder is mostly used in the prior art, and the most effective method at present is to adopt the hanging bag method, but there are still certain problems in the hanging bag method, such...
