Embodiment Construction

[0021] A temperature-sensitive sustained-release pesticide modified based on wheat bran ferulic acid sugar ester is characterized in that it consists of the following raw materials in parts by weight: 4 parts of ferulic acid, 13 parts of starch, an appropriate amount of dimethyl sulfoxide, and 2 parts of toluenesulfonic acid, 9 parts of sodium bicarbonate, appropriate amount of anhydrous ether, 22 parts of N-piperidine acrylamide, appropriate amount of deionized water, 3 parts of sodium lauryl sulfate, 26 parts of pesticide active ingredients, azo 4 parts of diisobutyronitrile, 2 parts of tetramethylethylenediamine, 6 parts of wheat bran fiber, 21 parts of oxalic acid.

[0022] Specific steps are as follows:

[0023] (1) Extraction of wheat bran ferulic acid sugar ester:

[0024] Prepare a 0.05% aqueous solution of oxalic acid, add it to an Erlenmeyer flask filled with wheat bran fiber, heat and hydrolyze it at 100°C for 5 hours, collect the supernatant by centrifugation, whe...

Abstract

The invention discloses a temperature-sensitive type controlled-release pesticide modified based on wheat bran ferulic acid glycolipid. The temperature-sensitive type controlled-release pesticide comprises the following raw materials in parts by weight: 2-5 parts of ferulic acid, 9-15 parts of starch, a proper amount of dimethyl sulfoxide, 1-3 parts of p-toluene sulfonic acid, 3-10 parts of sodium dicarbonate, a proper amount of absolute ether, 17-26 parts of N-piperidine acrylamide, a proper amount of deionized water, 2-5 parts of lauryl sodium sulfate, 20-32 parts of active ingredient of pesticide, 2-6 parts of azodiisobutyronitrile, 1-2 parts of tetramethylethylenediamine, 3-7 parts of wheat-bran fiber, and 18-27 parts of oxalic acid. The starch ferulate is synthesized by taking ferulic acid and starch as raw materials, free radical polymerization reaction is generated together with N-piperidine acrylamide to obtain temperature-sensitive type hydrogel, and reversible expansion and contraction can be generated by utilizing the change along with environment temperature, so that the sustained and stable release of active ingredient of pesticide can be realized, and the temperature-sensitive type controlled-release pesticide can achieve the purposes of being long-acting, reducing pollution and economically controlling oriental fruit moth.

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 based on modified wheat bran ferulic acid sugar ester 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 in the thic...
