example 1

[0020] Example one: get each 1 gram of dichlorvos, chlorpyrifos, isothion-methyl, Spodoptera litura nuclear polyhedrosis virus preparation (200,000,000 PIB / ml), 0.3 gram of camphor essential oil, 5 grams of ethanol as fumigation entraining agent, all the other use Mixed activated carbon and peat to make up to 100 grams. The fumigant is prepared according to the following method: Step 1, pulverizing activated carbon powder and peat powder through a 30-mesh sieve, and mixing the two at a weight ratio of 1:1; Step 2, mixing dichlorvos, chlorpyrifos, methylisothion, The camphor essential oil is mixed and dissolved in the fumigation entrainer; step 3, the mixture obtained in step 2 and the mixture obtained in step 1 are mixed uniformly;

[0021] Step 4: Add 20 grams of water to the mixture obtained in Step 3, extrude and granulate, and dry the obtained solid particles to prepare a fumigant.

[0022] In the case of lack of one of dichlorvos, chlorpyrifos, and isothion-methyl, or th...

example 2

[0024] Example two: get 1.5 grams of dichlorvos, 1.5 grams of chlorpyrifos, 1.5 grams of methyl isothion, 1.5 grams of Spodoptera litura nuclear polyhedrosis virus preparation (200 million PIB / ml), 0.5 grams of camphor essential oil, 8 grams of fumigation entrainer, All the other make up to 100 grams with the activated charcoal and peat that mix, just carry out by the step of example one.

[0025] In the case of lack of one of dichlorvos, chlorpyrifos, and isothion-methyl, or the absence of two components at the same time, the amount of the missing part is filled with an adsorptive carrier, and a control drug is made according to the dosage and method of the above-mentioned preparation. Under the condition that the dosage per mu is the same as 2 kg, the application is withdrawn in the field at the 3-5 leaf stage of corn, and the control effect on the two-spotted armyworm is as follows:

[0026]

example 3

[0027] Example three: get 2 grams of dichlorvos, 2 grams of chlorpyrifos, 2 grams of methylisothion, 2 grams of Spodoptera litura nuclear polyhedrosis virus preparation (200 million PIB / ml), 0.8 grams of camphor essential oil, 10 grams of fumigation entrainer , the rest are replenished to 100 grams with the mixed activated carbon and peat, and can be carried out according to the steps of Example 1.

[0028] In the case of lack of one of dichlorvos, chlorpyrifos, and isothion-methyl, or the absence of two components at the same time, the amount of the missing part is filled with an adsorptive carrier, and a control drug is made according to the dosage and method of the above-mentioned preparation. When the amount per mu is the same as 2 kg, it is applied in the field at the 3-5 leaf stage of corn, and the control effect on the two-spotted armyworm is as follows:

Abstract

The invention relates to a fumigation agent in the field of pesticide, in particular to a fumigation agent for preventing and controlling athetis lepigone as well as a preparation method of same. Aiming at the defects of low safety, heavy environmental pollution, short duration, high prevention and control cost and the like in the method for preventing and controlling the athetis lepigone, the invention provides the fumigation agent with high safety, high pesticide effect, high stability, light environmental pollution, long duration and low prevention and control cost.

Description

technical field [0001] The invention relates to a fumigant in the field of pesticides, in particular to a fumigant for preventing and treating Spodoptera bispotae and a preparation method thereof. Background technique [0002] In 2005, Athelis lepigone was first found to damage summer corn in Hebei Province, and gradually expanded its damage. More than 30 million mu occurred in Jiangsu and other places, becoming the main pest in today's production and seriously threatening the safety of food production. [0003] The adult moths like to move and lay eggs in hidden moist places, and the larvae also like to move in hidden moist places and harm crop seedlings. In recent years, mechanized wheat harvesting and stubble sowing of summer corn have been generally realized in the Huanghuaihai summer corn production areas, and the stalks after wheat harvesting are directly scattered to the fields, which provides a large area of ​​favorable conditions for the occurrence and damage of th...
