Problems solved by technology

[0005] Long-term use of one type of insecticide will easily lead to insect resistance, which will increase the amount of insecticide used, kill a large number of natural enemies of pests, increase the cost of insecticide, and pollute the environment, resulting in high toxicity, large dosage, large residues, and poor efficacy.
In the inventor's experiment, it was unexpectedly found that the dual compound preparation of biopesticide lepimectin and neonicotinoid insecticide can solve the above problems very well, with less dosage, high control effect, and more environmental protection of biopesticide, and this type of pesticide compound With no relevant reports

Embodiment approach

[0014] In the following technical scheme, component A is selected from the biological pesticide lepimectin, and component B is selected from any one of the neonicotinoid insecticides imidacloprid, acetamiprid, nitenpyram, thiamethoxam, and clothianidin.

[0015] In one of the technical solutions of the present invention, the insecticidal composition is an emulsion in water, and the weight percentage of the components is:

[0016] Active ingredient A 1~65%

[0017] Active ingredient B 1~80%

[0018] Emulsifier 3~30%

[0019] Solvent 5~15%

[0020] Antimicrobial agent 0.1~1%

[0021] Stabilizer 2~15%

[0022] Antifreeze 2~5%

[0023] Defoamer 0.1~8%

[0024] Thickener 0.2~2%

[0025] water balance

[0026] The specific production steps of the emulsion in water are as follows: first, the original medicine A and B, solvent, emulsifier, and cosolvent are added together to dissolve into a uniform oil phase; Pesticide auxiliaries are mixed together to form a uniform water ph...

[0082] (1) Test drug

[0083] 85% lepimectin and 93% imidacloprid are provided by Qingdao Hailier Pharmaceutical Group.

[0084] Dissolve the original drug with acetone first, and mix the appropriate amount of the two original drugs into 5 different ratios according to the results of the preliminary experiment, and then use acetone to dilute each treatment into 5 series of concentration gradients for use. The ratios of the active ingredients of the five lepimectin and imidacloprid in different proportions were 1:29; 3:27; 5:25; 7:23; 9:21, respectively, and were diluted into 5 series of concentration gradients for use.

[0085] (2) Test target

[0086] Wheat aphids were collected from the field population of the wheat experimental field of Qingdao Agricultural University, and wingless adult aphids of the same individual size were selected for testing.

[0087] (3) Test method

[0088] The spot method recommended by NY / T 1154.1-2006 was used for determination. Clean the mic...

[0115] It can be seen from the table that in different proportions of mixing, the co-toxicity coefficients are all greater than 120, showing a certain synergistic effect, wherein the synergistic effect of lepimectin: acetamiprid is the most obvious at 3:15, and the co-toxicity The coefficient is 136.39. The test results showed that under indoor conditions, acetamiprid and ...

Abstract

The invention relates to an insecticidal composition, which belongs to the field of composite insecticides. The insecticidal composition comprises the following two active components: biological pesticide lepimectin and neonicotinoid insecticide in a percentage ratio by weight of (1-65) to (80-1), preferably (1-35) to (40-1). The total mass percentage of the active components in the insecticidal composition is 1-90%, preferably 5-50%, and the rest components of the insecticidal composition are acceptable auxiliary components that are allowed to be used in pesticide. The insecticidal composition can be made into aqueous emulsion, microemulsion, emulsifiable concentrate, suspension, wettable powder or water dispersible granules through a known method. The insecticidal composition provided by the invention can be used for preventing and controlling aphid, plant hopper, white flies, leaf hopper and other homoptera insects with sucking mouth parts as well as cabbage moth, beet armyworm, tobacco cutworm, cotton bollworm, rice stem borer, mealy bug and other lepidopterous insects.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition which uses biopesticide lepimectin and neonicotinoid compounds as active ingredients. Background technique [0002] The biopesticide lepimectin is a derivative of milbemycin (milbemycin) A3 / A4 discovered by Sankyo Corporation of Japan. It is used as a new type of insecticide for vegetables and fruits such as cabbage, tomato, citrus, strawberry and grape, mainly to control Lepidoptera and Homoptera and other pests. The drug has the characteristics of high insecticidal activity, less dosage, safe for humans and animals, no environmental pollution, strong specificity, no harm to natural enemies, and not easy to produce resistance, etc. It can be used in rotation with abamectin insecticides, In case of abamectin resistance. Therefore, it is known as one of the most promising broad-spectrum, high-efficiency, new non-cross-resistance insectic...
