Temperature-sensitive type slow-releasing pesticide for trapping and killing oriental fruit moths by utilizing phototaxis and preparation method thereof

Abstract

The invention discloses a temperature-sensitive type slow-releasing pesticide for trapping and killing oriental fruit moths by utilizing phototaxis. The temperature-sensitive type slow-releasing pesticide is prepared from the following raw materials in parts by weight: 2 to 5 parts of fumalic acid, 9 to 16 parts of starch, a proper amount of dimethyl sulfoxide, 1 to 4 parts of p-toluenesulfonic acid, 3 to 12 parts of sodium hydrogen carbonate, a proper amount of anhydrous ethyl ether, 16 to 25 parts of N-piperidineacrylamide, a proper amount of de-ionized water, 2 to 5 parts of sodium dodecyl sulfate, 19 to 28 parts of a pesticide active component, 2 to 6 parts of 2,2'-azodiisobutyronitrile, 1 to 2 parts of tetramethylethylenediamine, 2 to 6 parts of light-induced energy-storage fluorescent powder and 1 to 3 parts of a fluorescent dyestuff. According to the temperature-sensitive type slow-releasing pesticide disclosed by the invention, the fumalic acid and the starch are used as the raw materials for synthesizing starch ferulate; the starch ferulate and the N-piperidineacrylamide are subjected to a free radical polymerization reaction to prepare temperature-sensitive type hydrogel; the temperature-sensitive type hydrogel can be reversibly expanded and retracted along the changes of environment temperature, so that the pesticide active component can be continuously and stably released; the aims that the effect is lasting, the pollution is reduced and the oriental fruit moths are economically controlled are realized.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a temperature-sensitive slow-release pesticide that utilizes phototaxis to trap and kill small pear borer worms and a preparation method thereof. Background technique [0002] Fruit tree borer is a general term for moth larvae that bore into fruits and damage them. There are more than 10 common species such as small pear borer, small peach borer, peach borer, and large pear borer. They are a type of frequent pests in fruit tree production. Among them, the small pear borer is also known as the small pear borer moth, the oriental fruit beetle moth, and the peach tip moth, etc., referred to as "little", which can harm a variety of fruit trees such as pears and stone fruits, such as pears, apples, peaches, and plums. Fruits and shoots of other fruit trees. In the central part of my country, there are 5 generations a year, and the mature larvae mainly cocoon ...
