Abstract

The invention discloses a cyromazine liquid preparation comprising the following components: 1-10 percent (W / V) of cyromazine, 5-30 percent (W / V) of stabilizer, 0-10 percent (W / V) of cosolvent, 0.1-1percent (W / V) of antioxidant and 100 percent (W / V) of dispersion medium. The invention also discloses a preparation method of the cyromazine liquid preparation. The cyromazine liquid preparation is asolution and the cyromazine in the solution can kill screwworms, stop screwworms from propagating in animal stalls, thereby improving the growing environment of animals. The cyromazine liquid preparation can be mixed with feed or drinking water and the greatly-improved degree of uniformity degree of mixture is greatly improved in comparison with matched feed; and the cyromazine liquid preparationdoes not influence the pesticide effect of the cyromazine; in addition, the cyromazine liquid preparation is convenient to use.

Description

technical field [0001] The invention relates to a cyromazine solution preparation, and also relates to a preparation method of the preparation. Background technique [0002] Cyromazine is a high-efficiency insect growth regulator. When the content of insects is higher than the normal amount, it can induce morphological distortions in the larvae and pupae of Diptera insects, resulting in incomplete eclosion or inhibition of adults. Therefore, it can It has a killing effect on the larvae of Diptera insects, especially has a good inhibitory and killing effect on several common larvae such as fly maggots that reproduce in feces, and mainly controls the reproduction of fly larvae in animal stables. The difference between cyromazine and general fly-killing medicines is that it only kills larvae - fly maggots, while general fly-killing medicines only kill adult flies and are more toxic. After cyromazine enters the animal body, the vast majority (about 99%) is excreted with the fec...
