Embodiment 1

[0035] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0036] Test method: The rice stem dipping method is adopted. Pull out the strong rice plants from the tillering stage to the early booting stage, wash them, cut them into 15 cm long rooted rice stems, set them in groups of 3, and let them dry in the air until there is no water mark. Soak the rice stems in the diluted medicine for 30 seconds, take them out and dry them, wrap the roots with soaked absorbent cotton and put them into the finger tubes, absorb the 3rd instar larvae and put them into the finger tubes, 20 heads per tube, Set soaked water as the blank control, and each concentration was repeated 3 times. After treatment, put them in an observation room at 27°C with a photoperiod of 16h:8h (L:D). The number of deaths was checked regularly, and the corrected death rate was calculated using the Abbott formula. Calculate the lethal middle concentration LC of each test single agent by...

Embodiment 2

[0048] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0049] Test method is the same as embodiment one

[0050] The test results are shown in Table 2.

[0051] Table 2 Toxicity results of acetochlor and acetamiprid against rice planthopper

[0052] Drug name

[0053] Acetocilin: acetamiprid = 19:1

[0054] The measurement results showed that the co-toxicity coefficients of the three combinations of acetochlor and acetamiprid against rice planthoppers were all above 120, which indicated that the combination of acetochlorin and acetamiprid had obvious synergistic effects on rice planthoppers.

Embodiment 3

[0056] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0057] Test method is the same as embodiment one

[0058] The test results are shown in Table 3.

[0059] Table 3 Toxicity results of acetoallin and thiamethoxam to rice planthopper

[0060] Drug name

[0061] The measurement results showed that the co-toxicity coefficients of the three combinations of acetochlorin and thiamethoxam to rice planthoppers were all above 120, indicating that the combination of acetoallin and thiamethoxam had a better synergistic effect on rice planthoppers. effect.

Abstract

The invention provides an ethylicin-containing pesticidal composition. The pesticidal composition is composed of an effective component (ethylicin) and a neonicotinoid insecticide (imidacloprid, acetamiprid, thiamethoxam, thiacloprid, nitenpyram, dinotefuran or clothianidin), and in combination with auxiliary components such as additives and carriers and the like which are usually used in pesticides, the pesticidal composition can be processed into micro-emulsions, wettable powder and water dispersible granules. By using the pesticidal composition provided by the invention, a higher synergistic effect can be generated, the production of drug resistance of pests can be reduced and delayed, and the service life of a pesticide variety can be prolonged. The composition provided by the invention can be used for preventing and controlling various homoptera and thysanoptera injurious insects and the like on rice, vegetables and fruit trees and the like, especially can be used for preventing and controlling rice planthopper, aphids, whiteflies, scale insects, thrips, rice gall midges, and the like; and meanwhile, the pesticidal composition also can be used for treating crop diseases such as rice blasts, cotton fusarium wilts, and the like.

Description

technical field [0001] The invention relates to an insecticidal composition and its application, in particular to a compound composition containing acetoallin and neonicotinoid insecticidal components. The invention can be used for controlling rice planthopper, aphid, whitefly, scale insect, thrips, rice gall midge and the like. Background technique [0002] Rice planthoppers, aphids, whiteflies, scale insects, thrips, rice gall midges and other pests are important pests on rice, vegetables, fruit trees, cotton and other crops. These pests have a large reproduction rate and obvious generation overlap. In recent years, due to single and unscientific use of pesticides, these pests have developed resistance to varying degrees, and pests and diseases of the same crop often occur at the same time. Increase the amount of medicine, etc., resulting in increased costs for farmers, environmental pollution and damage to the ecological environment. Combining two ingredients with diffe...
