Insecticide composition for preventing and treating borers and preparation method as well as application thereof

Abstract

The invention discloses an insecticide composition for preventing and treating borers and a preparation method as well as application thereof, belonging to the fields of new formulations of pesticides and preparation thereof. The pesticide suspending agent consists of the following components in percentage by weight: 1-50 percent of spirotetramat, 0.5-20 percent of avermectin, 3-15 percent of wetting dispersant, 2-8 percent of anti-freezing agent, 0.1-3 percent of thickening agent, 0.01-6 percent of stabilizer, 0.1-2 percent of preservative, 0-10 percent of penetrant, 0.01-2 percent of anti-foaming agent and the balance of water. The various components in the proportion are ground in a sand mill at the rotation speed of 1,000-15,000 r / min for 2-3 hours to keep that the particle sizes are all below 5 mum, so that the pesticide suspending agent is obtained; and the pesticide suspending agent is diluted by a factor of 1,000-15,000 and then sprayed to leaves for killing off various borer eggs. The suspending agent has the advantages of high safety, low cost, high effect and safety to crops.

Description

technical field [0001] The invention belongs to the field of new pesticide formulations and preparation thereof, and in particular relates to a pesticide suspension containing spirotetramat and abamectin, a preparation method and application thereof. Background technique [0002] There are many kinds of borers, which are the main pests that harm fruit trees in northern my country. They mainly include small pear borer, pear large borer, peach small borer (peach fruit moth), white small borer, plum small borer, peach borer and cotton bollworm, etc. , can harm a variety of fruit trees such as pome fruit and drupe fruit, such as the fruits of pears, apples, peaches, plums and other fruit trees and the tender shoots of peaches, plums, borer cherries, apples and other fruit trees. In the central part of my country, there are 5 generations a year, and the mature larvae mainly cocoon in the thick glumes of the branches and survive the winter. Pupation begins in March of the followin...

Problems solved by technology

④Chemical control mainly uses macrolides (such as abamectin, emamectin benzoate, etc.), pyrethroids (such as lambda-cyhalothrin, bifenthrin, etofenproxil, etc.) etc.), organophosphates (such as chlorpyrifos, malathion, etc.), carbamates (such as carbosulfan, carbosulfan, etc.), benzamides (such as chlorantraniliprole, fluoride Bifendiamide, etc.), benzoylureas (such as hexaflumuron, lufenuron, diflubenzuron, thiflumuron, etc.) Prevention and control, but the patents that have been applied for are all for the prevention and treatment of borer larvae or adults, and there is no report on the patent of the borer ovicide

However, abamectin is easy to decompose when exposed to light, has poor persistence, and is prone to resistance when used alone
