Abstract
The present invention relates to a high-efficiency insecticidal duple powder and a preparation method thereof, particularly to a paddy rice field pesticide improved by an insecticidal duple aqueous agent in the form of powder and a preparation method thereof. The present invention is especially suitable for preventing and eliminating various injurious insects in paddy rice fields, such as yellow rice borers, striped rice borers, purplish rice borers, rice plant skippers, rice leaf folders, etc. The high-efficiency insecticidal duple powder is prepared from an insecticidal duple aqueous agent through drying, wherein the effective component is hydrated dimethylamino-1, 3-disodium thiosulfate propane, and the rest components are sodium chloride, sodium thiosulfate, water and a filling material. The preparation method of the insecticidal duple powder comprises: proportionally mixing the insecticidal duple aqueous agent with the filling material; filling the mixture in a spraying nozzle in a dry chamber by a pump; atomizing the mixture, and then heating the mixture by hot air for vaporizing and drying the mixture so as to obtain the high-efficiency insecticidal duple powder.
Description
What bisultap powder of the present invention and preparation method thereof related to is a kind of paddy field insecticide, through improved pulvis and manufacture method thereof, be particularly useful for preventing and kill off various pests such as paddy field paddy stem borer, striped rice borer, pink rice borer, rice plant skipper, leaf-roller by dimehypo water solution.
Existing paddy field insecticide variety is more, but great majority are to belong to aqua and emulsion, and also having only a few is to belong to hypertoxic class agricultural chemicals, medication is careless a little, and people and animals are easy to generate intoxication accident, and we are processed into the former medicine of desinsection list at the eighties research dimehypo water solution, to reduce survival dose, increase insecticidal effect, shortcoming is that dimehypo water solution still has a certain amount of ratio, the packing charges of dimehypo water solution is big, should not transport for long-distance, not storage endurance, degraded easily, consumption is big, and insecticidal effect is poor.
The objective of the invention is provides a kind of bisultap powder and preparation method thereof at above-mentioned weak point, adopt new technology dimehypo water solution is made bisultap powder, improve effective content, thereby reduced the dimehypo water solution packing charges, overcome the big difficulty of freight volume, be the insecticidal activity height, a kind of new type disinsection pulvis that effective, application process is easy, have greater activity.
Bisultap powder and preparation method thereof takes following scheme to realize: contain the effective ingredient dimehypo in the dimehypo water solution, chemical name is the two thiosulfonic acid sodium base propane C of dimethylamino-1,3-

3, water.Bisultap powder adopts the dimehypo water solution drying to make.Active ingredient hydration dimethylamino-1, the two thiosulfonic acid sodium base propane of 3-are 40～60% (percentage by weights) in the bisultap powder, all the other composition sodium chloride contents are 15～25% (percentage by weights), sodium thiosulfate content is 6～10% (percentage by weights), water content is 1～5% (percentage by weight), and filer content is 8～20% (percentage by weights).Filler is one or more the mixture in kaolin, white carbon, potassium chloride, sodium bicarbonate, the sodium chloride.
Bisultap powder preparation method: dimehypo water solution, filler are mixed stirring by being pumped to the nozzle that is located in the Pressuresprayingdrier drying room by the proportioning weighing,,, make bisultap powder through the hot air evaporation drying with the feed liquid atomizing.
Bisultap powder is compared with the dimehypo water solution that tradition is used, and good disinsection effect can be prevented and treated paddy rice important pests such as paddy rice paddy stem borer, striped rice borer, rice plant skipper and rice leaf roller effectively, and is easy to use, and peasant household is easy to grasp and accepts.Test through indoor and outdoor, comprehensive safety, drug effect, factors such as usage amount show, the optimum content of dimehypo is 40～60% in the bisultap powder, through Jiangsu, plant protection such as Jiangxi and agricultural chemicals identify that administrative department carries out the field control effectiveness test comparation and assessment, product insecticidal activity height of the present invention, under every mu of prerequisite with bisultap powder 60～100g, to leaf-roller, the integrated control effect of snout moth's larva is 70.5～100%, be 87～100% wherein to the control efficiency of leaf-roller medication after 2 days, the control efficiency of medication after 5 days is 79.1～96.5%, the control efficiency of medication after 10 days is 71.2～99.24%, control efficiency to snout moth's larva also reaches 70.51～100%, apparently higher than dimehypo water solution.Bisultap powder adopts the dimehypo water solution drying to make, its preparation method simple and reliable process, easy to prepare, cost is low.Because bisultap powder is made in the dimehypo water solution change, improved the dimehypo effective component content, thereby reduced packing charges, overcome the big difficulty of freight volume, and have efficient, low toxicity, long characteristics of lasting period, through outdoor test, the insect of phosphorus wing order there is special efficacy, insecticidal effect reaches about 95%.
The invention will be further described below with reference to embodiment.
