Embodiment 1

[0015] Embodiment 1 Contains the effect of fluofos pesticide composition on cabbage beet armyworm

[0016] Beet armyworm collected in the field was used in the experiment, which was used for the experiment after two generations of breeding. The specific method is as follows:

[0017] Leaf disc preparation: select clean bracts, wash and dry them, and use a puncher to make leaf discs for later use.

[0018] Drug preparation: Before the test, the original drug was prepared into different concentrations according to the proportioning scheme.

[0019] Dipping: Use tweezers to pick up the leaf discs and dip them in the liquid medicine for 5 seconds, take them out and dry them on absorbent paper, and put them in a 24-well plate after air-drying naturally, with 2 pieces per well. A total of 3 plates were placed for each concentration treatment.

[0020] Inoculation: Put one 3rd instar larva of beet armyworm in each well of a 24-well plate, cover it and place it in an insect culture...

Embodiment 2

[0029] Example 2 Effect of Pesticide Composition Containing Piflufos on Spider Mite

[0030] Insect test: Broad bean seedlings are used indoors to raise Tetranychus cinnabarinus all year round. Before the test, stick double-sided tape on one end of the glass slide, and use a brush to select the multiplied adult mites of the same age and paste them on the tape. Post about 50 heads and put them in a 9cm petri dish covered with filter paper for moisturizing. After 2 hours, the microscopic examination was carried out, and the dead worms were discarded.

[0031] Drug preparation: Before the test, the original drug was prepared into different concentrations according to the proportioning scheme.

[0032] Immersion: Start with a low concentration, pick up the glass slide with tweezers, immerse the end with the mite in the solution of the concentration series to be tested, shake gently for 3 seconds, take it out, filter the liquid and absorb the excess with absorbent paper solution,...

Embodiment 3

[0040] Embodiment 3 Contains the effect of the pesticide composition of flufenfos on banana root-knot nematode

[0041] Mix sterilized soil and sterilized river sand to form culture soil, mix thoroughly, and then mix into the medicine. The concentration of the agent is calculated in milligrams of the active ingredient of the agent per kilogram of soil. Use the corresponding quantitative preparation to mix the soil directly. After mixing thoroughly, add water to make the water content 30%. 20d banana seedlings were transplanted into pots, and 7 days after transplanting, 500 root-knot nematode 2nd instar larvae were inserted into each pot, placed in a greenhouse, and routinely managed. 6 pots were treated with each drug, and they were set as blank control. After 40 days, the number of root knots in each pot was investigated, and graded according to Liu Weizhi (1995): level 0, no root knots; level 1, 1-2 root knots; level 2, 3-10 root knots; level 3, 11-30 knots; level 4, 31-10...

Abstract

The invention discloses a flupyrazofos-containing pesticide composition which comprises a component A with effective dose and a component B, wherein the component A is flupyrazofos, the component B is one or more selected from abamectin, pleocidin, emamectin benzoate, ivermectin, beta cypermethrin, cyhalothrin, tefluthrin, beta-cyfluthrin, fipronil and chitosan oligosaccharide, and the mass percentage rate of component A to component B is (30:1)-(1:30). The flupyrazofos-containing pesticide composition is applied to crops or crop parts to prevent and treat injurious insects, injurious mites or nematodes on plants of agriculture, horticulture or forestry.

Description

technical field [0001] The present invention relates to a pesticide composition, in particular to a synergistic composition containing pyraflufos and having excellent effects on agriculture, gardening, forest pests, pest mites and nematodes. Background technique [0002] Flupyrazofos is a new organophosphorus insecticide, which has excellent control effects on various crop pests, especially on Lepidoptera pests. In order to reasonably protect pesticides, delay the emergence of pest resistance to new pesticides and improve the control effect of pesticides, it is necessary to conduct reasonable compound research. Currently, there are few researches on compound insecticides containing flufos, but the present invention discovers a pesticide composition containing flufos with obvious synergistic effect through experiments. Contents of the invention [0003] The object of the present invention is to provide a pesticide composition containing pyrofalfos for preventing and contro...
