Description
Technical Field
The invention belongs to the field of pesticides, particularly relates to the field of agricultural insecticides, and particularly relates to a pesticide insecticidal composition and application thereof.
Background
The pesticide variety containing a single active component has defects of different degrees in the prevention and control of agricultural pesticides, such as narrow pesticide range, poor prevention and control effect, high pesticide application dosage, easy generation of pesticide resistance, multiple application times, environmental pollution and the like. For controlling pests which generate resistance in agriculture, one method is to deduce a new component which has no cross resistance with the existing variety, but the development cost of the new effective component is high, the development period is long, and the speed of generating resistance by the pests can not be kept up with all the time. Other methods such as crop layout adjustment, rotation of different pesticides, etc. are difficult to really play an obvious role in the actual operation process.
The abamectin is a macrolide antibiotic insecticide, has high biological activity to pest mites and pests of various crops, and has the characteristics of spectrum, high efficiency, low residue, safety to people, livestock and environment and the like. The action mechanism of the pesticide is different from that of common pesticides in that the pesticide interferes with the neurophysiological activity, stimulates the release of gamma-aminobutyric acid, and the aminobutyric acid has an inhibitory effect on the nerve conduction of arthropods. The insect larvae are in contact with the abamectin to generate paralysis, and die after 2 to 4 days without eating. The abamectin is adsorbed in soil and cannot move, and is decomposed by microorganisms, so that the abamectin has no accumulation effect in the environment and can be used as a component of comprehensive control.
The dicyclopropionate is a novel pesticide jointly developed by Nippon Mingzhi pharmaceutical company and Nippon North Ri research institute, has a brand-new action mechanism, has a good lethal effect on piercing-sucking pests such as aphids, plant hoppers, scale insects and leafhoppers, can be used for vegetables, fruit trees, intertillage crops, ornamental plants and the like, has a good effect on leaf surface treatment, planting treatment and soil treatment, and has low toxicity.
The compounding of different kinds of components is the most common method for controlling resistant pests. The different components are compounded, so that the control effect can be improved, the control range is expanded, the using amount of the effective components is reduced, the pesticide cost is saved, the environmental pollution is reduced, and the method is an important means for comprehensively controlling acarid pests. When the abamectin and the dicyclopropionate are used singly, the abamectin and the dicyclopropionate both have certain defects and limitations. At present, no compound medicine of the two medicines exists, and the combination effect of other insecticides for preventing and controlling mite pests is not ideal.

As can be seen from table 1, the composition of the embodiment of the present invention has high activity on red spiders, the avermectin and the dicyclopropyl tetramethrin have obvious synergistic effect within a mass portion ratio of 50:1 to 1:50, the co-toxicity coefficient (CTC) is above 120, and particularly the mass portion ratio is 1: 1-10, the co-toxicity coefficient (CTC) is above 160, and the synergistic effect is remarkable. Therefore, the compounding of the abamectin and the amitraz has reasonability and feasibility.
To better illustrate the effective control effect of the present invention, the above example agents, 20% of propiconazole and 5% of avermectin suspending agent are used for field pesticide effect control of cabbage aphid, and the test results are shown in the following table 2.
The field efficacy test is designed to carry out 5 treatments of medicament, contrast medicament, clear water and the like, and the area of each test cell is 50m2Cells are randomly arranged every 4 repetitions of processing. 0.5m protection rows are arranged between each cell and around the test field. The cabbage was applied by manual spraying, 1 time before application, 1 time after 3 days, 7 days and 14 days after application, and 4 times in total. The investigation method adopts a five-point sampling method. And (3) surveying 10 crops at fixed points in each cell, surveying population base number and residual population, and calculating population decline rate and control effect. The calculation formula is as follows:
oral cavity decline rate (%) [ (number of insects before application-number of insects after application)/number of insects before application ] × 100
Control effect (%) [ (treatment area population reduction rate-blank control area population reduction rate)/(1-blank control area population reduction rate) ] × 100
Corrected control effect (%) [ (control effect in treatment area-control area)/(control effect in 100-control area) ] × 100
TABLE 2 control of aphids on cabbage by different treatments
The test results in table 2 show that the control effect of the applied medicament on the cabbage aphids is obviously higher than that of the comparative medicament; after 14 days of pesticide application, the control effect of the pesticide on the cabbage aphids is still over 90 percent, and the control effect of the pesticide is up to 98 percent in some cases. The result shows that the compound pesticide of the abamectin and the diproprionate has obvious synergistic action and the lasting time is obviously longer than that of a single pesticide. Experiments show that the compound composition obviously reduces the using amount of the medicament, and reduces the production cost, the pesticide residue and the environmental pollution. In addition, field observation during the test period shows that the liquid medicine of each treatment of the medicament in the embodiment has no influence on the growth of crops, is safe to surrounding beneficial organisms and has good environmental compatibility. Therefore, the abamectin and the dicyclopropyl tetramethrin are ideal compound insecticidal products.
