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, propylsulfur, etc.), benzamides (such as chlorantraniliprole, fluoride Bifendiamide, etc.), benzoylureas (such as hexaflumuron, lufenuron, diflubenzuron, thiflumuron, etc.) 防治,专利号为CN102265878A、CN1299595A、CN1305711A、CN101720777A、CN101700025A、CN102084862A、CN102428951A、CN102100235A、CN102326571A、CN102318629A、CN102326582A、CN102246762A的中国专利文件,记载的都是防治食心虫幼虫或成虫的药物,未见食心虫杀卵 agent reports
However, if spirotetramat is used alone, it is easy to produce resistance, and the control cost is high

Embodiment 1

[0039]Embodiment 1: 5% spirotetramat 5% mineral oil suspoemulsion

[0040] The content of each component (by weight) is: spirotetramat 5%, mineral oil 5%, wetting and dispersing agent sodium dodecylbenzene sulfonate 10%, emulsifier EO-PO block copolymer 5%, Antifreeze agent propylene glycol 4%, thickener hydroxyethyl cellulose 0.1%, preservative sodium benzoate 0.5%, silicone defoamer 0.1%, stabilizer linseed oil 2%, add deionized water to 100%. After mixing, grind in a sand mill for 2 hours, so that the particle size is all below 5 μm to obtain a pesticide suspoemulsion containing spirotetramat and vegetable oil, mineral oil or paraffin oil.

Embodiment 2

[0041] Embodiment 2: 10% spirotetramat 3% vegetable oil suspoemulsion

[0042] The content of each component (by weight) is: spirotetramat 10%, methylated vegetable oil 3%, wetting and dispersing agent sodium lignosulfonate 10%, emulsifier nonylphenol polyoxyethylene ether (NP series) 5%, antifreeze ethylene glycol 5%, thickener xanthan gum 0.2%, preservative benzoic acid 0.5%, silicone defoamer 0.2%, stabilizer epoxy soybean oil 5%, add deionized water to 100 %. After mixing, grind in a sand mill for 2.5 hours, so that the particle size is all below 5 μm to obtain a pesticide suspoemulsion containing spirotetramat and vegetable oil, mineral oil or paraffin oil.

Embodiment 3

[0043] Embodiment 3: 5% spirotetramat 1% mineral oil suspoemulsion

[0044] The content of each component (by weight) is: spirotetramat 5%, mineral oil 1%, wetting and dispersing agent lauryl polyoxyethylene ether phosphate 15%, emulsifier fatty alcohol polyoxyethylene ether (AEO series) 3%, antifreeze agent glycerol 4%, thickener hydroxyethyl cellulose 0.1%, preservative sodium diacetate 0.5%, silicone defoamer 0.1%, stabilizer citric acid 3%, plus deionization Water to 100%. After mixing, grind in a sand mill for 3 hours, so that the particle size is all below 5 μm to obtain a pesticide suspoemulsion containing spirotetramat and vegetable oil, mineral oil or paraffin oil.

Abstract

The invention discloses a pesticide suspension emulsion containing spirotetramat and vegetable oil or mineral oil or paraffin oil as well as a preparation method and application thereof, and belongs to the field of pesticides. The suspension emulsion comprises the following components in percentage by weight: 1-40% of spirotetramat, 0.5-20% of vegetable oil (or mineral oil or paraffin oil), 3-15% of wetting dispersant, 1-10% of emulsifier, 2-6% of anti-freezing agent, 0.1-3% of thickener, 1-10% of stabilizer, 0.1-2% of preservative, 0.01-2% of defoamer and 100% of water. The preparation method comprises the steps of: sanding the components except the emulsifier, the vegetable oil (or mineral oil or paraffin oil) and the water to particles with particle sizes below 5 microns; uniformly mixing the emulsifier and the vegetable oil (or mineral oil or paraffin oil) and then adding into the water, and carrying out high shearing for 5-20 minutes; and mixing the particles and the solution to obtain the suspension emulsion. The pesticide suspension emulsion can be sprayed on leaf surfaces to kill the eggs of pod borers after being diluted for 1000-6000 times. The suspension emulsion is good in safety, low in cost, good in pesticide effect and safe for crops.

Description

technical field [0001] The invention belongs to the field of new pesticide dosage forms and preparation thereof, and specifically relates to a pesticide suspoemulsion containing spirotetramat and vegetable oil, mineral oil or paraffin oil, 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. Pupat...
