Problems solved by technology

[0002] Because of its strong reproductive ability, short life cycle and frequent occurrence all year round, citrus spider mite is very easy to develop resistance to acaricides and the efficacy of the drug is significantly reduced. At present, chemical agents are used to control citrus spider mite. There are still the following difficulties to be overcome: the drug has a short duration of action, and although it can achieve a good effect after application, it often breaks out again after three to five days; the drug is highly toxic and the drug residue is serious

Embodiment 1

[0008] Embodiment 1: Abamectin, etoxazole and flubenzuron and different proportioning are to the virulence determination of citrus Panonychus

[0009] 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 ...

Embodiment 2

[0019] Embodiment 2: the preparation method of 20% abamectin · etoxazole · flubenzuron suspension concentrate and medicament field test

[0020]

[0021]

[0022] 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.

[0023] The preparation of this embodiment is used to prevent and control Panonychus citrus in the sugar orange orchard. The test time is August 2014. The conventional foliar spray is used to uniformly prevent and 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, 7 days and 21 days after spraying, an...

Embodiment 3

[0028] Embodiment 3: the preparation method of 8% abamectin · etoxazole · flubenzuron microemulsion and medicament field test

[0029] 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.

[0030] The formulation of this example is used to prevent and control harmful mites in Aomise citrus orchards. The test time is June 2014. During the application of the pesticide, there are many adult mites in the field. The conventional foliar spray is used for uniform control, and the leaves are wet. . 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,...

Abstract

The invention relates to a method for preventing and treating citrus red mites. Avermectin, etoxazole and flufenoxuron are blended according to a weight ratio of 1-2: 3-5: 5-10, then the obtained mixture is diluted with water, and the diluted mixture is uniformly sprayed on the leaves of citrus. According to the invention, avermectin, etoxazole and flufenoxuron with different action mechanisms are rationally combined to prepare a pesticide composition; the pesticide composition is applied to prevention and treatment of citrus red mites, shows obvious synergistic effect, greatly improves pesticide effect and reduces the usage amount of pesticide per mu, so adverse influence on environment and pesticide residues are reduced, the lasting time of drug effect is prolonged, and the disadvantage of easy incurrence of drug resistance of a single component of the pesticide composition is overcome.

Description

technical field [0001] The invention relates to the technical field of agricultural planting management, in particular to a method for preventing and treating citrus red spiders. Background technique [0002] Because of its strong reproductive ability, short life cycle and frequent occurrence all year round, citrus spider mite is very easy to develop resistance to acaricides and the efficacy of the drug is significantly reduced. At present, chemical agents are used to control citrus spider mite. There are still the following difficulties to be overcome: the drug has a short duration of action, and although it can achieve a good effect after application, it often breaks out again after three to five days; the drug is highly toxic and the drug residue is serious. Contents of the invention [0003] The purpose of the present invention is to provide a method with high efficiency, low toxicity, good quick effect and long lasting effect, which can effectively control citrus red ...
