Problems solved by technology

In terms of pesticides that are actually sprayed on crop targets, only 20-30% of traditional pesticide formulations are effectively used, which not only causes economic waste, but also causes large-scale environmental pollution

Embodiment 1

[0015] A temperature-sensitive pesticide sustained-release agent for the prevention and treatment of peach heartworm, which comprises the following components by mass: 0.8-1.3 parts of beta-cypermethrin, 0.4-1.0 parts of N-piperidine acrylamide, and hydroxypropyl methyl fiber 0.4-1.0 part of N-maleylated chitosan, 0.2-0.4 part of sodium persulfate, 0.2-0.4 part of sodium metabisulfite, 0.2-0.4 part of sodium lauryl sulfate and deionized water 35 -65 copies.

[0016] A method for processing the above-mentioned temperature-sensitive pesticide sustained-release agent for preventing and treating peach heartworm, including the following steps:

[0017] (1) 0.2-0.4 parts by mass of sodium lauryl sulfate is dissolved in 10-20 parts by mass of deionized water to obtain a mixed solution, and then the mixed solution is mixed with 0.8-1.3 at a rotation speed of 1500-3000 rpm. Mass parts of beta-cypermethrin are mixed to form a dispersion;

[0018] (2) 0.4-1.0 parts by mass of N-piperidine acr...

Embodiment 2

[0021] (1) Weigh 0.3 g of sodium lauryl sulfate and dissolve in 10 g of deionized water, and disperse 0.8 g of lambda cypermethrin in it at a rotation speed of 2000 rpm to form a dispersion liquid I.

[0022] (2) Weigh 0.650 g of N-piperidine acrylamide, 0.650 g of hydroxypropyl methyl cellulose, and 0.08 g of N-maleated chitosan to completely dissolve in 70.0 g of deionized water to form an aqueous solution II.

[0023] (3) After nitrogen is introduced into the aqueous solution II, 0.010 g of sodium metabisulfite, 0.012 g of sodium persulfate, and dispersion I are added to the aqueous solution II, sealed in a glass reaction vessel in a 60°C water bath for cross-linking polymerization, After continuous reaction for 5 hours, cool, rinse with deionized water, and vacuum-dry to constant weight to obtain.

[0024] The sustained-release effect of a temperature-sensitive slow-release agent of lambda cypermethrin obtained according to the steps in this example and the sustained-release effe...

Abstract

The invention discloses a thermosensitive pesticide slow release agent for preventing and treating carposina niponensis walshingham. The thermosensitive pesticide slow release agent comprises the following materials in parts by weight: 0.8-1.3 parts of beta-cypermethrin, 0.4-1.0 part of N-piperdinyl acrylamide, 0.4-1.0 part of hydroxypropyl methylcellulose, 0.2-0.4 part of N-maleoyl chitosan, 0.2-0.4 part of sodium persulfate, 0.2-0.4 part of sodium metabisulfite, 0.2-0.4 part of sodium dodecyl sulfate and 35-65 parts of deionized water. This invention selects N-piperdinyl acrylamide as a monomer material and hydroxypropyl methyl cellulose as an interpenetrating material to synthesize an interpenetrating polymer network so as to improve the defects of polypiperdinyl crylamide. In an IPN hydrogel, no chemical bonds are available between N-piperdinyl acrylamide and hydroxypropyl methyl cellulose. The polymers are relatively dependent. The characteristic of mutual independence and interdependence determines the special properties of the IPN hydrogel, so that the interpenetrating polymer network polymer generated effectively improves the original defects of polypiperdinyl crylamide.

Description

Technical field [0001] The invention belongs to the technical field of pesticide production, and specifically relates to a pesticide slow-release agent which is highly sensitive to external temperature and is used for the prevention and treatment of peach heartworm. Background technique [0002] With the increasing awareness of environmental protection and food safety in the whole society, the negative impact of the production and use of pesticides on the environment has attracted increasing attention, environmental protection regulations have become increasingly stringent, and the threshold for pesticide residue limits in agricultural products has continued to increase. Challenges are coming more and more severe. In the "Twelfth Five-Year Plan" of the pesticide industry, "vigorously promote the development of pesticide formulations in the direction of water-based, dust-free, controlled release and other high-efficiency and safety" as a key task in the future. Some safe, economi...
