Problems solved by technology

Flubenzuron has a relatively poor quick-acting effect, but has a good long-lasting effect and is safe for predatory mites and insects
[0006] Abamectin, etoxazole, and flubendron have different mechanisms of action, and the acaricidal composition with abamectin, etoxazole, and flubendron as active ingredients has no control application for preventing and treating citrus spider mite. Related reports

Embodiment 1

[0013] Example 1: Toxicity determination of avermectin, etoxazole and flubenzuron and different ratios to Panonychus citrus

[0014] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". The female adults of Panonychus citrus collected from the field were reared indoors for 30 generations, and the female adults with uniform growth were selected as the test insects. Adopt the small seedling method, that is, inoculate 50-60 heads of all claw mites on small pots of citrus seedlings, check the base number one day later, pick out dead mites, and add live adult mites, and keep the number of mites for each treatment at about 50. Spray the seedlings with mites using a spray tower, move them to culture at 25°C and 90% relative humidity, check after 15 days, record the number of survivors, use DPS data processing software for statistical analysis, calculate the regression curve, and calculate the LC 50 , using the co-toxicity coeffi...

Embodiment 2

[0024] Embodiment 2: the preparation method of 20% abamectin·etoxazole·flubenzuron suspension concentrate and medicament field test

[0025]

[0026] According to the requirements of the formula, the above components are uniformly mixed according to the amount of the formula, and ground by a sand mill to obtain a 20% abamectin·etoxazole·flubenzuron suspension concentrate.

[0027] The preparation of this example is used to prevent and control Panonychus citrus in the sugar orange orchard. The test site is Shuangqiao Town, Wuming County, Nanning, Guangxi. The test time is August 2014. The conventional foliar spray is used for uniform control, and the leaves are wet. . There were more adult mites of Panonychus spp. in the field when the pesticide was applied. A total of 4 treatments were set up in the experiment, and each treatment was repeated 4 times. The insect population base in the field was investigated before spraying, and the insect situation was investigated 1 day,...

Embodiment 3

[0032] Embodiment 3: the preparation method of 8% abamectin·etoxazole·flubenzuron microemulsion and medicament field test

[0033] Weigh 1.0% Abamectin, 3.0% Etoxazole, 5.0% Flubenzuron, 4% TX-10, 5% Nongru 700#, 6% Nongru 500#, 3% Nongru 1601#, 15% Cyclohexanone, 5% N-methylpyrrolidone, 5% n-butanol, 1% epichlorohydrin, completely dissolved and mixed uniformly, supplemented with deionized water to 100% by weight, and stirred uniformly to obtain 8% albino Vermectin·etoxazole·flubenzuron microemulsion.

[0034] The formulation of this example is used to prevent and treat Panonychus citrus in the sugar orange orchard. The test site is in a sugar orange orchard in Baisha Town, Yangshuo County, Guilin City, Guangxi. The test time is June 2014. There are more adults of Panonychus in the field during application. , use conventional foliar spray for uniform control, subject to leaf moistness. A total of 4 treatments were set up in the experiment, and each treatment was repeated 4 t...

Abstract

The invention relates to a pesticide composition containing etoxazole and flufenoxuron. Abamectin, etoxazole and flufenoxuron serve as effective constituents, and the weight ratio of abamectin to etoxazole to flufenoxuron in the composition is 1-2:3-5:5-10. Abamectin, etoxazole and flufenoxuron of different action mechanisms are reasonably mixed to prevent and treat citrus red mites, have an obvious synergetic effect and can greatly improve the pesticide effect and reduce pesticide dosage per mu, so that undesirable influences on the environment and pesticide residues are reduced, the duration of the pesticide effect is prolonged, and meanwhile the defect that resistance to a single-dosage pesticide is likely to occur is overcome.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to an acaricidal composition containing etoxazole and flubenzuron, which is used for preventing and controlling harmful mites of citrus trees. Background technique [0002] Citrus spider mite, also known as Citrus Panonychus, belongs to Acaridae and Tetranychidae. It is distributed in Sichuan, Yunnan, Guangxi, Guangdong and other provinces. It gathers adults and nymphs on leaves, twigs and peels to absorb juice, often causing massive Symptoms such as leaf fall, spotted fruit, and fruit drop. Due to its strong reproductive ability, short life cycle, and frequent attacks all year round, red spiders are very easy to develop resistance to acaricides and the efficacy of the drugs is significantly reduced. Therefore, compounds with new acaricidal sites and different mechanisms of action are developed The combination of specific pesticides is the best way to solve the problem of resistance. [...
