Problems solved by technology

Polyphagous pests mainly harm seedlings with larvae. The larvae bite off the stems of the seedlings near the ground, causing the death of the whole plant, resulting in lack of seedlings and broken ridges, seriously affecting crop yield

Embodiment 1

[0017] Embodiment one: Indoor toxicity test

[0018] Test insects: third-instar cutworm larvae with the same individual size and physiological state were reared indoors for generations.

[0019] Drugs to be tested: tefluthrin and sulfoxaflor.

[0020] Test method: The spot method is used for determination, referring to the "People's Republic of China Agricultural Industry Standard NY / T1154.1-2006", the specific method is as follows.

[0021] Firstly, clean the micro-dropper with solvent, and adjust the dropper to standby state. Then use a brush to select neat and consistent test insects and use CO 2 After being mildly paralyzed, place it in a 9cm petri dish, and finally use a micro-dropper to drip the medicine head by head onto the abdomen of the worm body, dripping 0.5 μL of the drug solution on each head, and taking the treatment of dripping 0.5 μL of the corresponding acetone as a control, the dripping The final test insects were placed in an intelligent insect culture r...

Embodiment 2

[0030] Example 2: Preparation of 6% tefluthrin·sulfoxaflor granules

[0031] The following substances are all percentages by weight: 5% tefluthrin, 1% sulfoxaflor, 8% corn starch, 6% gum arabic, 2% quartz sand, and the balance of kaolin.

[0032] Mix the above materials evenly in the blending kettle, granulate through high tower coating, dry at 40°C-70°C until the water content of the particles is less than 3%, sieve, the particle size range is 2000μm-4000μm, and after passing the inspection, it is The desired 6% tefluthrin·sulfoxaflor granule was obtained.

Embodiment 3

[0033] Embodiment three: Drug efficacy test

[0034] Drugs for testing:

[0035] (1) Test agent: 6% tefluthrin·sulfoxaflor granules (5:1);

[0036] (2) Control agents: 5% tefluthrin granules, 1% sulfoxaflor granules

[0037] Control object: peanut cutworm

[0038] Application method: spraying before sowing

[0039] Test time: March 21, 2014

[0040] Test location: Yanhu Village, Renshan Town, Huidong County, Guangdong Province

[0041] Table 2 of the test results shows that 6% tefluthrin·sulfoxaflor granules are more effective in controlling peanut cutworms than 5% tefluthrin granules and 1% sulfoxaflor granules, and are safe for peanuts.

[0042] Table 2. Field efficacy test results of tefluthrin and sulfoxaflor combination granules in controlling peanut cutworm.

Abstract

The invention discloses a tefluthrin and sulfoxaflor containing pesticide composite and application thereof. The tefluthrin and sulfoxaflor containing pesticide composite comprises tefluthrin and sulfoxaflor serving as active ingredients, and the balance of pesticide adjuvants, wherein the mass part ratio of the tefluthrin and sulfoxaflor in the pesticide composite is 50:1-1:50; the total mass of the tefluthrin and the sulfoxaflor accounts for 0.1 to 40 weight percent in the pesticide composite. The pesticide composite disclosed by the invention is prepared into particles in actual use, and is suitable for preventing peanut cutworms.

Description

technical field [0001] The invention relates to a pesticide composition, which uses tefluthrin and sulfoxaflor as active ingredients and is used for preventing and controlling peanut cutworms. Background technique [0002] Cutworms belong to the family Noctuidae of the order Lepidoptera, and there are more than 10 species of cutworms that cause damage to agricultural crops. Among them, small cutworms, yellow cutworms, large cutworms, white-bordered cutworms and police-striped cutworms are particularly important. Polyphagous pests mainly harm the seedlings with larvae. The larvae bite off the stems of the seedlings near the ground, causing the death of the whole plant, resulting in lack of seedlings and broken ridges, seriously affecting crop yield. [0003] Tefluthrin is a pyrethroid insecticide, which is a soil insecticide, which can well control Coleoptera, Lepidoptera and some Diptera pests that inhabit the soil, and can control pumpkin twelve-star beetle , needleworm, f...
