Problems solved by technology

[0004] At present, the use of spinosad synergists for the control of armyworms mostly uses the compounding of various pesticides, such as the mixed use with chlorpyrifos. Since the potential risk of the same or similar mechanism of action cannot be ruled out for these neurotoxins, cross-resistance is very low. It is easy to produce, and it cannot avoid residual pollution to the environment and crops. At present, no green synergist that enhances spinosad activity has been found and applied.

Embodiment

[0019] Embodiment: A kind of drug synergist for preventing and controlling armyworm and its application method

[0020] 1.1 Armyworms tested

[0021] Armyworm 2nd instar larvae.

[0022] 1.2 Concentration ratio of cyclosporine A and spinosad

[0023] The concentration of spinosyn was 0.5 mg / L, which was mixed with different concentrations of cyclosporine A (50 μM and 100 μM).

[0024] 1.3 Bioassay methods

[0025] What this application adopts is medicament mixed artificial feed (yeast powder 34 g, wheat germ powder 40 g, corn leaf powder 100 g, mix well; 2, sorbic acid 2 g, methylparaben 4 g, 300 mL distilled water boil and mix After uniformity, add the mixture into ① and mix well; 3. 600 mL distilled water, 18 g agar powder, boil and mix well, add to ②, stir well; 4. When the temperature drops to 40°C, add VC 2.5g, sub 5-6 drops of oleic acid (soybean oil), mix well; store at 5, 4°C.) for bioassay. That is, the armyworm artificial diet was prepared first, and spinosad or...

Abstract

The invention belongs to the field of toxicological activity of pest control, and particularly relates to a drug synergist for preventing and treating mythimna separata and a using method of the drugsynergist. The drug synergist for preventing and treating mythimna separate is cyclosporin A, wherein a medicine is spinosad, wherein the mythimna separata is a two-year-old larva. The method for preventing and treating the mythimna separata by utilizing the drug synergist comprises the following steps: mixing the spinosad with a certain concentration with cyclosporin A, then mixing with an artificial feed of the mythimna separata again, and then feeding. The cyclosporin A disclosed by the invention has a remarkable effect of preventing and treating mythimna separata by the spinosad, and can be used as a synergist for preventing and treating mythimna separata by the spinosad so as to improve the prevention and treatment effect of agricultural pests by the spinosad.

Description

technical field [0001] The invention belongs to the field of toxicological activity of pest control, in particular to a drug synergist for preventing and controlling armyworm and its application method. Background technique [0002] Armyworm ( Mythimna separata (Walker)), belonging to Lepidoptera Noctuidae, also known as shaving insects, marching insects, commonly known as multicolored insects, wheat silkworms, is a heterogeneous polyphagous mainly eating wheat, corn, sorghum, rice and other food crops and pastures , migratory, intermittent explosive pests. It can harm more than 104 species of plants in 16 families, especially gramineous plants. Except for some areas in the Northwest, it is distributed in other places. When armyworm outbreaks occur, crop leaves can be eaten up, causing serious damage to crop growth. In recent years, armyworm outbreaks have frequently occurred in various places, causing huge damage to agricultural production, especially corn production. ...
