Embodiment 1

[0018] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0019] Test method: The rice stem dipping method is adopted. Root out the robust 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

[0031] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0032] The test method is the same as biological example 1.

[0033] The test results are shown in Table 2.

[0034] Table 2 Toxicity results of oxymatrine and acetamiprid compound against rice planthopper

[0035] Drug name

[0036] The test results show that the co-toxicity coefficients of the three combinations of oxymatrine and acetamiprid to rice planthoppers are all above 120, indicating that the combination of oxymatrine and acetamiprid has a significant synergistic effect on rice planthoppers .

Embodiment 3

[0038] Test object: 3rd instar nymphs of brown planthopper (Nilaparvata lugens Stal).

[0039] The test method is the same as biological example 1.

[0040] The test results are shown in Table 3.

[0041] Table 3 Toxicity results of oxymatrine and thiamethoxam to rice planthopper

[0042] Drug name

[0043] The measurement results showed that the co-toxicity coefficients of the three compounding ratios of oxymatrine and thiamethoxam to rice planthoppers were all above 120, indicating that the compounding of oxymatrine and thiamethoxam showed a significant increase in rice planthoppers. effect.

Abstract

The invention relates to a pesticide composition containing oxymatrine. The pesticide composition is characterized in that the pesticide composition contains oxymatrine and an anabasine pesticide; the anabasine pesticide is imidacloprid, acetamiprid, nitenpyram, thiamethoxam, thiacloprid, dinotefuran or clothianidin; and after being blended with such auxiliary ingredients generally used in the pesticides as auxiliaries, carriers and the like, the pesticide composition can be processed into microemulsion, wettable powder and water dispersible granules. The pesticide composition has the following beneficial effects: the pesticide composition can have a better synergistic effect, reduce and delay generation of drug resistance of pests and prolong the service lives of pesticide varieties; and the composition can be used for controlling various homoptera and thysanoptera pests on the rice, vegetables, fruit trees and the like, especially for controlling rice plant hopper, aphids, whiteflies, scale insects, thrips, rice gall midge and the like.

Description

technical field [0001] The invention relates to an insecticidal composition and its use, in particular to a compound composition containing oxymatrine and neonicotinoid insecticidal ingredients. 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 chemical pesticides are still used as the main control species in agricultural and forestry production, causing environmental pollution and ecological environment damage. The research and development of biopesticides has become a hot spot in the sustainable...
