Problems solved by technology

In recent years, chlorfenapyr has been widely used in the control of vegetable pests, and has a good control effect on diamondback moth and cabbage caterpillar. However, chlorfenapyr is highly toxic to fish and shrimp, and its use in water networks and lake areas is subject to certain restrictions.
At the same time, the quick effect of chlorfenapyr is poor and the price is high

Embodiment 1

[0016] In order to verify the insecticidal effect of different ratios of chlorfenapyr and tebufenozide on vegetable pests, the indoor toxicity test of different ratios of chlorfenapyr and tebufenozide on cabbage caterpillars was carried out, and the corresponding formulas were formulated according to the weight percentages in the table. Concentration, indoor contact insecticide test was carried out to determine the co-toxicity coefficient, and the co-toxicity coefficient measurement results of different ratios of chlorfenapyr and tefenozide are shown in the table:

[0017]

[0018] The measurement results show that the co-toxicity coefficients of the compound agents of chlorfenapyr and tebufenozide in different proportions of the present invention are all greater than 100, and all have obvious synergistic effects.

Embodiment 2

[0019] Example 2: Preparation of 10% chlorfenapyr·tefenozide wettable powder

[0020] Chlorfenapyr 3%

[0021] Tebufenozide 7%

[0022] NNO (dispersant) 3%

[0023] Sodium lignosulfonate (dispersant) 7%

[0024] Sodium alkylbenzene sulfonate (dispersant) 1%

[0025] Silica (filler) 79%

[0026] Weigh the materials according to the above weight ratio, add each material in turn under stirring, pulverize through the jet mill and stir and mix evenly to obtain the product, carry out the field efficacy test of preventing and controlling vegetable cabbage caterpillar, the efficacy is better, and the control effect is 85%. above.

[0027] The following table is the 7-day control effect (%) statistical table of 10% chlorfenapyr · tebufenozide wettable powder in the control of cabbage leaf moth:

[0028]

[0029] The above test results show that 10% chlorfenapyr·tefenozide wettable powder has a good killing effect on cabbage leaf moth, and the average control effect is abov...

Embodiment 3

[0030] Example 3: Preparation of 10% chlorfenapyr·tebufenozide wettable powder

[0031] Chlorfenapyr 3%

[0032] Tebufenozide 7%

[0033] NNO (dispersant) 3%

[0034] Sodium lignosulfonate (dispersant) 7%

[0035] Sodium alkylbenzene sulfonate (dispersant) 1%

[0036] Silica (filler) 79%

[0037] Weigh the materials according to the above weight ratio, add each material in turn under stirring, pulverize through a jet mill, stir and mix evenly to obtain the product. The field efficacy test of controlling vegetable aphids was carried out, and the efficacy was good, with an average control efficiency of more than 80%.

[0038] The following table is the statistical table of 10% chlorfenapyr · tebufenozide wettable powder against aphids for 2-14 days:

Abstract

The invention discloses a synergistic pesticide containing chlorfenapyr and tebufenozide, and relates to the technical field of production of synergistic pesticide compositions. The synergistic pesticide comprises the following raw materials in percentage by weight: 1 to 20 percent of chlorfenapyr, 1 to 20 percent of tebufenozide, 2 to 25 percent of auxiliary agents and 35 to 96 percent of filler. A production method of the synergistic pesticide comprises the following steps of: adding the raw materials into a porcelain enamel stirring kettle and uniformly mixing; and jet-milling or grinding to prepare wettable powder or suspension, namely the synergistic pesticide composition containing the chlorfenapyr and the tebufenozide. After the chlorfenapyr and the tebufenozide are compounded, the synergistic pesticide has low toxicity, low residue, a wide bactericidal spectrum and high persistence, is low in cost, and is an ideal high-efficiency low-toxicity pesticide preparation for preventing and controlling various diseases of vegetables.

Description

technical field [0001] The invention relates to the technical field of synergistic insecticidal composition production. Background technique [0002] Vegetable pests are an important cause of harm to vegetable production. In recent years, although the state has banned the use of highly toxic pesticides on vegetables, there are often poisoning incidents caused by eating vegetables containing highly toxic pesticide residues. Therefore, the development of high-efficiency, low-toxic, low-toxic Pesticide residues are an inevitable development trend. [0003] Chlorfenapyr is a new type of pyrrole insecticide and acaricide. It has a wide insecticidal spectrum, has gastric poisoning and contact killing effects on various insect pests such as Homoptera, Orthoptera, Hemiptera, Thysanoptera and Coleoptera, and is safe for crops. It has the advantages of long duration and low dosage. In recent years, chlorfenapyr has been widely used in the control of vegetable pests, and has a good ...
