Abstract

Provided is a solution type water based pesticide which comprises, 30 to 40 wt% of a propellent, 6 to 10 wt% of alcohol, 48 to 63 wt% of purified water, 0.01 to 2 wt% of raw pesticides, 0.05 to 6 wt% of synergists and a proper amount of a corrosion inhibitor, wherein the alcohol is methanol or ethanol, the propellent is dimethyl ether, the raw pesticides are selected from synthetic pyrethroids or carbamates or a mixture of the two, and the synergists are 1-n-butylazaheptane-2-ketone, 1-n-octylazaheptane-2-ketone, piperonyl butoxide, normal paraffins and a composition thereof.

Description

(1) Technical field [0001] The invention relates to a novel insecticide formulation, in particular to a solution-type water-based insecticide suitable for spraying. (2) Background technology [0002] For a long time, people have used dichlorvos, DDT, trichlorfon and other insecticides to kill sanitary pests. However, these insecticides often cause certain harm to human health and livestock safety while killing mosquitoes and flies. These insecticides are not only highly toxic, but also emit special irritating odors, which are easy to cause certain pollution to the living environment. Butane and other organic solvents and propellants are prepared, resulting in the danger of flammability and explosion in the product. [0003] Existing insecticidal aerosols are generally oil-based insecticidal aerosols with kerosene as a solvent, which will leave an unpleasant kerosene smell indoors after spraying, and the sprayed droplets are easy to leave on the surface of objects. Therefor...
