Problems solved by technology

However, high-efficiency cyhalothrin mainly prevents pests such as Lepidoptera and Coleoptera, and is ineffective against mites
Therefore, the control of the patented composition against harmful mites is still achieved through spiromethin, which cannot improve its control effect against harmful mites

Embodiment 1

[0031] Example 1: The control effect test of the acaricidal composition of the present invention on citrus spider mite

[0032] The test was carried out in an orchard of a farmer in Zhengzhou, Henan. The acaricidal composition was mixed with spiromethin, triazotin, propargite, tetrafenazine or pyridaben. The test treatments and application rates are shown in Table 1. The acaricidal composition and the single doses of each component are all dissolved in clear water before application.

[0033] Table 1 Test treatment and application rate

[0034]

[0035] Choose 4 trees of the same size for each treatment, choose leaves from 5 orientations of east, south, west, north, and middle for each tree, 10 leaves in each orientation, and repeat 4 times for each treatment. The number of citrus red spiders was recorded in the post-medication survey, and the control effect was calculated. The results are shown in Table 2.

[0036] Among them, the calculation formula is as follows:

[0...

Embodiment 2

[0042] Example 2: Control effect test of the acaricidal composition of the present invention on citrus ticks

[0043] With reference to the test method of Example 1, the control effect test of citrus ticks was carried out on the acaricidal composition of the present invention. The test treatments and application rates are the same as in Table 1, and the control effect calculation method is the same as in Example 1. The results are shown in Table 3.

[0044] Table 3 The control effect of the acaricidal composition of the present invention on citrus ticks

[0045]

[0046] It can be seen from the results in Table 3 that the dosage of the active ingredient spiromethifen was mixed with one of triazotin, propargite, tetrafenazine or pyridaben, compared with the single dose of each ingredient, but the activity after application The number of insects is significantly reduced, the rate of insect population decline is high, and the corrected control effect is 5-10% higher than the c...

Embodiment 3

[0047] Example 3: The control effect test of the acaricidal composition of the present invention on apple spider mite

[0048] With reference to the test method of Example 1, the citrus tick control effect test was carried out on the acaricidal composition of the present invention. The test treatments and application rates are the same as in Table 1, and the control effect calculation method is the same as in Example 1. The results are shown in Table 4.

[0049] Table 4 The control effect of the acaricidal composition of the present invention on citrus ticks

[0050]

[0051] It can be seen from the results in Table 4 that the dosage of the active ingredient spiromethifen was mixed with one of triazotin, propargite, tetrafenazine or pyridaben, compared with the single dose of each ingredient, but the activity after application The number of insects is significantly reduced, the rate of insect population decline is high, and the corrected control effect is 5-10% higher than ...

Abstract

The invention relates to the field of pesticide preparations and discloses a mite-killing composition. The mite-killing composition consists of spiromesifen and one of azocyclotin, propargite, clofentezine or pyridaben, wherein the weight ratio of the spiromesifen to the azocyclotin, propargite, clofentezine or pyridaben is 1-99:99-1. The invention also discloses a mite-killing preparation for controlling mites of farmlands and fruit trees, and the active ingredient of the mite-killing preparation is the mite-killing composition which accounts for 1 to 99 percent of the weight of the mite-killing preparation. The mite-killing composition and the preparation thereof have the advantages of obviously improving mite-controlling efficiency, reducing the amount of active ingredients, delaying the generation of drug resistance of mites and lowering environmental pollution, has an obvious synergistic effect, and can be widely applied to agricultural fields.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to an acaricidal composition and its preparation. Background technique [0002] Acarids are commonly known as "red spiders" or "ticks", and belong to the class Arachnida and the subclass Acari. The body length of mites is usually less than 2mm. The head, thorax and abdomen are fused together without body segments. They are divided into two body segments, the jaw body and the body. Most nymphs and adults have 4 pairs and breathe through the trachea. There are about 500,000 species of acarids in the world, among which the agricultural pests mainly include spider mites, spider mites, barb mites, tarsal mites and gall mites. There are more than 500 kinds of agricultural pest mites in my country, of which more than 40 are seriously harmful, such as citrus spider mites, citrus ticks, apple spider mites, etc. They mainly harm fruit trees and cotton, wheat, vegetables, tobacco, tea, ...
