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 red spider citrus

[0032] The experiment was carried out in a farmer’s orchard in Zhengzhou, Henan. The acaricide composition was mixed with spiromesifen, triazotin, propargyl, tetramazine or pyridaben, and the test treatment and application amount are shown in Table 1. The acaricidal composition and each component single agent are dissolved in clear water and then applied.

[0033] Table 1 Test treatment and dosage

[0034]

[0035] Choose 4 trees of the same size for each treatment, and choose the leaves in 5 positions of east, south, west, north, and middle for each tree, and 10 leaves in each position. Repeat 4 times for each treatment, respectively before and after application. The post-medicine survey recorded the number of citrus red spiders and calculated the control effect. The results are shown in Table 2.

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

Embodiment 2

[0042] Example 2: The 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 acaricidal composition of the present invention was tested for the control effect of citrus tick. The test treatment and dosage are the same as Table 1, and the control effect calculation method is the same as that of 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] From the results in Table 3, it can be seen that the effective ingredients of spiromesifen and one of triazotin, proparginate, tetramazine or pyridaben are mixed, and the dosage is reduced compared with the single dose of each ingredient, but the active ingredient is active after application. The number of insects is obviously reduced, the rate of insect population reduction is high, and the corrected control effect is higher than 5...

Embodiment 3

[0047] Example 3: Control effect test of the acaricidal composition of the present invention on apple spider mites

[0048] With reference to the test method of Example 1, the acaricidal composition of the present invention was tested for the control effect of citrus tick. The test treatment and dosage are the same as Table 1, and the control effect calculation method is the same as that of 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 effective ingredients of spiromesifen and one of triazotin, propargyl, tetramazine or pyridaben are mixed, and the dosage is reduced compared with the single dose of each ingredient, but the active ingredient is active after application. The number of insects is obviously reduced, the rate of insect population reduction is high, and the corrected control effect is higher than 5-1...

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 preparations thereof. Background technique [0002] Mites are commonly known as "red spiders" or "ticks" and belong to the class Arachnida and Acarina. The body length of mites is usually less than 2mm. The head, chest and abdomen are healed into one body without body segments. They are divided into two body segments, the jaw body and the body. Most nymphs and adult mites have 4 pairs of feet and breathe through the trachea. There are about 500,000 species of tick mites in the world. Among them, the agricultural pest mites mainly include spider mites, spider mites, thin mites, tarsal mites, and gall mites. There are more than 500 types of agricultural pest mites in my country, of which more than 40 are serious, such as citrus red spiders, citrus ticks, apple spider mites, etc. They mainly damage fruit trees and cotton, wheat, vegetables, tobacco, t...
