Problems solved by technology

[0005] In the control of mango thrips, imidacloprid is one of the most commonly used medicaments, but because of its long-term single use, the resistance of mango thrips to it is increased, and the drug effect is reduced. The new product that delays the development of its resistance can effectively control the damage of mango thrips and ensure the stable and bumper harvest of crops

Embodiment 1

[0018] Example 1: Indoor toxicity determination of cyantraniliprole, carbosulfan and different ratios on mango tea yellow thrips

[0019] Test drug: 94% of the original drug of cyantraniliprole (DuPont, USA); 90% of the original drug of carbosulfan (Hubei Sanonda Co., Ltd.), the original drug was prepared into the required test drug according to the conventional method .

[0020] Test object: Mango tea yellow thrips, collected from the suburbs of Tianyang County, Guangxi, and raised with potted mango seedlings indoors.

[0021] Test method: The test refers to the "Agricultural Industry Standards of the People's Republic of China" (Pesticide Indoor Bioassay Test Guidelines for Insecticides NY / T1154.14-2008), and the leaf soaking method is used. Cut the fresh and tender mango (green) leaves into 5mm*20mm strips, soak them in the prepared medicinal solution for 10 seconds, take them out and dry them fully in the shade, and put them into finger-shaped tubes (5cm high, 1cm inner d...

Embodiment 2

[0029] Example 2: 20% cyantraniliprole · carbosulfan suspension concentrate

[0030] Weigh 10% cyantraniliprole, 10% carbosulfan, 6% alkylphenol polyoxyethylene sulfonate, 6% sodium dodecylbenzenesulfonate, 1% C8-10 fatty alcohol, phenolic aldehyde Add 2% resin and deionized water to 100%, and mix to prepare 20% cyantraniliprole-spinosyn suspension concentrate.

Embodiment 3

[0031] Example 3: 15% cyantraniliprole Carbosulfan suspension concentrate

[0032] Weigh 10% cyantraniliprole, 5% carbosulfan, 6% ester polyoxyethylene, 5% Sapindus powder, 1.2% silicone, 2% methylcellulose, deionized water Add to 100%, and mix to prepare 15% cyantraniliprole-carbofuran suspension concentrate.

Abstract

The invention relates to a pesticide composition for preventing and controlling thrips of mangoes. The pesticide composition consists of cyantraniliprole and carbosulfan, wherein the weight ratio of the cyantraniliprole and to the carbosulfan is (1-3):(2-5). The pesticide composition has a synergistic effect, is suitable for prevention and control of the thrips of the mangoes, can effectively delay development of pest resistance, reduce the application amount of each piece of pesticide and improve the prevention and control effect, and is favorable for reducing chemical pesticide residue.

Description

technical field [0001] The invention relates to the technical field of pesticide application, in particular to a pesticide composition for preventing and treating mango thrips. Background technique [0002] Mango is one of the fruit trees planted in Guangxi. It will be threatened by diseases and insect pests during its growth. Among them, thrips is one of the main pests that harm mango. Thrips belong to Thysanoptera Thripidae. Young fruits and young leaves are especially harmful to young fruits. They often eat the peel at the base of the fruit and the side of the shade, causing scars and seriously affecting the commercial rate of the fruit. [0003] Cyantraniliprole (cyantraniliprole), chemical name: 3-bromo-1-(3-chloro-2-pyridyl)-N-[4-cyano-2-methyl-6-[(methylamino)hydroxy ]phenyl]-1H-pyrazole-5-carboxamide. Cyantraniliprole controls pests by activating the ryanodine receptors of target pests. Activation of ryanodine receptors releases stored calcium ions in striated and...
