Problems solved by technology

Kewojing prevents and treats snails by spraying, but its disadvantage is that the efficiency of killing snails is low, and the drug effect drops rapidly. It mainly has repelling effect on snails. The control effect of one application at the seedling stage is only 55-65%, and its dosage is large ( 260 g / mu), increasing the cost of pesticides, easily causing damage to crops, causing certain damage to beneficial natural enemies of humans, animals and pests, and easily causing pollution to the soil ecological environment
At present, snails and slugs are mainly prevented and controlled with granule poison baits at home and abroad. There are 6% of snails in China, 6% of mita and 2% of snail granules in foreign countries. Direct protective effect, due to the large dosage (500 g / mu), and it is sprinkled on the farmland, it has a certain poisonous effect on the beneficial natural enemies of the crops and poultry (chicken and duck, etc.)

Embodiment Construction

[0006] Below in conjunction with the examples the present invention is further described: embodiment 1 formula is: by weight copper sulfate pentahydrate content is 73.95%, amethocarb content is 0.05%, wettable powder additive WPA content is 2%, anhydrous carbonic acid The sodium content is 24%. Copper sulfate pentahydrate is dried and pulverized after weighing, so that it loses 8-11% of combined water, and then sprays it on the damaged crops after preparing a medicinal solution 1: 180-200 times with water; the formula of embodiment 2 is: The copper sulfate pentahydrate content by weight is 73.9%, the metcarb content is 0.1%, the WPA content is 1.5%, and the anhydrous sodium carbonate content is 24.5%, and all the other are the same as embodiment 1; embodiment 3 formula is: copper sulfate pentahydrate Content 76.8%, Methiocarb content 0.4%, WPA content 3.0%, Anhydrous sodium carbonate content is 19.8%, all the other are with embodiment 1; Embodiment 4 formula is: copper sulfate...

Abstract

The invention provides a pesticide for preventing mollusks such as snail and slug, which comprises cupric sulfate pentahydrate 70.0-78.5 wt%, meta-toly-N-methylcarbamate 0.05-0.55%, WPA 1.0-5.5%, and balancing anhydrous sodium carbonate (or other foreign matter). The medicament provided by the invention has strong eradication efficiency and long-acting prevention action.

Description

Technical field [0001] The invention is a high-efficiency pesticide for controlling molluscs such as snails and slugs. technical background [0002] Retrieve according to relevant data, also do not have at present the pesticide of preventing and treating snail slug identical with the formula of the present invention. At present, the pesticide for preventing and controlling snails has the name of invention called copper sulfate metacarb wettable powder (commercial name Ke Wo Jing, formerly known as Wo Ke), invention patent number: ZL94111510.0, which consists of copper sulfate pentahydrate, metacarb and anhydrous carbonic acid The sodium mixture is composed of the copper sulfate pentahydrate content of 77.7-80.2% by weight, the content of metcarb of 0.3-0.7%, and the rest is anhydrous sodium carbonate. Kewojing prevents and treats snails by spraying, but its disadvantages are that the efficiency of killing snails is low, and the drug effect drops rapidly. It mainly has a rep...
