Problems solved by technology

[0002] Nematodes, rice planthoppers, diamondback moths, flea beetles, red spiders, tea leafhoppers, thrips, beet armyworms, rice leaf rollers, aphids, whitefly, scale insects, rice gall midges, etc. are important crops. In addition, the pests and diseases of the same crop often occur at the same time. Farmers often lose sight of one another when controlling pests alone, not only delaying work but also missing the timing of control, thus increasing the amount of pesticides, etc., resulting in a decline in the quality of agricultural products.
In recent years, due to single and unscientific drug use, the resistance of pests and pest mites to active ingredients such as organophosphorus, neonicotinoids, carbamates, pyrethroids, etc. The drug resistance of the new ingredients in 2 years is also gradually increasing, which directly causes the increase of farmers' costs, environmental pollution and ecological environment damage, etc.

Embodiment 1

[0017] Embodiment 1 chitosan oligosaccharide and abamectin as synergistic component to the effect of organophosphorus insecticide

[0018] Taking organophosphorus pesticide components thiazophos and chlorazophos as examples, the effects of chitosan and avermectin compositions on thiazophos and chlorazophos as synergistic components were illustrated. Use sterilized soil and sterilized river sand to mix into culture soil, mix it into the composition or a single dose, mix well, add water to make the water content 40%, put it into a pot, and transplant the 20d cotton plants into the pot , 10 days after transplanting, 500 2nd instar larvae of Meloidogyne incognita were inserted into each pot, placed in the greenhouse, and managed with quantitative watering. Three repetitions were set for each treatment, and different single agent, binary compound agent and blank control were set. After 30 days, when there are a large number of root knots in the rhizosphere of the blank control pla...

Embodiment 2

[0022] Example 2 Chitooligosaccharide and Abamectin as synergistic components on the effect of neonicotinoids

[0023] Taking the neonicotinoid pesticide components nitenpyram and thiamethoxam as examples, the effect of chitosan oligosaccharide and abamectin composition as a synergistic component on nitenpyram and thiamethoxam was illustrated. When the rice seedlings are in the tillering stage to the booting stage, set up a test plot in the paddy field, and set up a plot of 50m for each treatment. 2 , each plot uses 5 points for listing, and each point is 1 clump, and the number of rice planthoppers is investigated. The agents are prepared accurately and diluted according to the concentration, and the rice seedlings are sprayed evenly from the tillering stage to the booting stage, and single agent, binary compound agent and blank treatment are set up. The number of rice planthoppers listed for treatment was investigated 7 days after the application, and the number of rice dwa...

Embodiment 3

[0027] Embodiment 3: The effect of oligochitosan and spinosad as synergistic components on amide insecticides

[0028] Taking amide pesticide ingredients cyantraniliprole and flunamide as examples, the effect of chitosan oligosaccharide and spinosad composition as a synergistic component on amide pesticides was illustrated. Before the experiment, divide the plots in the Chinese cabbage test site, list them, and investigate the number of diamondback moths and flea beetles on the listed plants in different plots. Accurately prepare different medicaments respectively, and carry out pre-drug dilution according to the dosage. Use a hand-held sprayer to evenly spray the cabbage in the plot, and set the corresponding drug control and blank control. Investigate the number of live insects listed for treatment in each community 1 day after the drug treatment, and observe the growth of cabbage 7 days after the drug treatment. The results are shown in Table 3.

Abstract

The invention discloses an insecticide acaricide taking an oligose and macrolides composition as a synergist, and in particular relates to a synergism composition capable of enhancing the insecticiding effect of the insecticide acaricide. The composition comprises oligose and a macrolides insecticide; the macrolides insecticide is abamectin, pleocidin, emamectin benzoate or ivermectin; the oligose is pectic oligosaccharide, sodium alginate oligosaccharides or chitosan oligosaccharide; the mass part ratio of the oligose to the macrolides insecticide is (1-30):(1-10). The synergism composition can enhance the insecticidal efficacy of the insecticide acaricide and realize the synergism effect with other insecticide acaricides.

Description

technical field [0001] The invention belongs to the field of plant protection, in particular to an insecticide and acaricide with an oligosaccharide and macrolide composition as a synergistic component and its application.
