Embodiment 1

[0016] Based on the weight of 100kg of the finished hot fog agent, 18kg of omethoate, 5kg of emulsifier, 5kg of alkylphenol polyoxyethylene ether, 1kg of calcium dodecylbenzenesulfonate, and 10kg of DMF were stirred to form a clear and transparent solution, and then supplemented with methyl naphthalene. To 100kg, stir and mix to obtain the finished preparation. Use Nantong Guangyi Electromechanical Co., Ltd. 6HY series fog machine spray test. The 18% omethoate EC produced by Guangxi Tianyuan Biochemical Co., Ltd. was used as the control agent, and the traditional method of spraying was used for control. According to the statistics, the average time per mu of the hot fog machine spraying method and the normal pressure spraying method are 3.5min and 152min respectively. The control effect results are shown in Table 1.

Embodiment 2

[0020] Based on the weight of 100kg of the finished product, stir 10kg of dichlorvos, 5kg of emulsifier, 5kg of alkylphenol polyoxyethylene ether, 1kg of calcium dodecylbenzenesulfonate, and 30kg of trimethylbenzene to form a clear and transparent solution, then make up to 100kg with diesel , Stir and mix uniformly to obtain a finished preparation. Use Nantong Guangyi Electromechanical Co., Ltd. 6HY series fog machine spray test. Take Jina EC (10% hyperosmolar dichlorvos EC) produced by Guangxi Tianyuan Biochemical Co., Ltd. as the control agent, and use the traditional method of spraying for control. According to the statistics, the average time per mu of the hot fog machine spraying method and the normal pressure spraying method are 3.2min and 145min respectively. The control effect results are shown in Table 2.

Embodiment 3

[0024] Based on the weight of 100kg of the finished product, stir 20kg of chlorpyrifos, 5kg of emulsifier, 5kg of alkylphenol polyoxyethylene ether, 1kg of calcium dodecylbenzenesulfonate, and 30kg of trimethylbenzene to form a clear and transparent solution, and then make up to 100kg with diesel , Stir and mix uniformly to obtain a finished preparation. Use Nantong Guangyi Electromechanical Co., Ltd. 6HY series fog machine spray test. Chlorpyrifos (480g / L hypertonic dichlorvos emulsifiable concentrate) produced by Guangxi Tianyuan Biochemical Co., Ltd. was used as the control agent and sprayed by traditional spraying methods. According to the statistics, the average time per mu of the two spraying methods of hot fog machine spraying method and atmospheric pressure spraying method is 4.1min and 161min respectively. The control effect results are shown in Table 3.

Abstract

The invention relates to a use of a hot fogging concentrate in a sugarcane field, in particular to a method for controlling pests and diseases of sugarcanes, which is characterized in that the hot fogging concentrate prepared by an insecticide is applied in the control of the pests and the diseases of the sugarcanes. The hot fogging concentrate consists of the raw insecticide, an additive, a solvent and a cosolvent. The application method adopts a hot fogging machine for spraying fog, the method is used for controlling sugarcane cottony aphid and other sugarcane pests, and the using process does not need to add water for dilution, the application efficiency is high and the control effect is significant. Compared with the traditional application method, the method can save a large number of human and material resources.

Description

technical field [0001] The invention relates to a method for controlling sugarcane cotton aphid and other sugarcane pests in a sugarcane field by using a thermal mist. Background technique [0002] Thermal fog was studied abroad earlier, but its development was slow, and most of its applications were in sanitation and epidemic prevention. Since 1965, my country has also successively developed dichlorvos hot spray and dichlorvos-malathion hot spray varieties, which are used for the prevention and control of insect pests in forestry and indoor mosquitoes, flies, bedbugs and other sanitary pests. At that time, there was not enough understanding of the requirements of dosage forms, medical equipment and application technology, and the application of the three was not closely combined for experimental research, so this dosage form was not popularized and applied on a large scale. In the 1980s, under the organization of the Ministry of Chemical Industry, with the close cooperatio...
