Chlorfenapyr composition for preventing and controlling crossocosmia sericariae as well as preparation method and application method of chlorfenapyr composition

Abstract

The invention discloses a chlorfenapyr composition for preventing and controlling crossocosmia sericariae. The chlorfenapyr composition comprises chlorfenapyr agent powder, an assistant and water. The invention discloses a preparation method of the chlorfenapyr composition for preventing and controlling crossocosmia sericariae. A suspending agent stoste containing chlorfenapyr is prepared from the chlorfenapyr powder after a certain ratio of assistant is added. The invention also discloses an application method of the chlorfenapyr composition. A solution containing 0.1-0.03% of chlorfenapyr effective component is prepared from the prepared suspending agent stoste according to the silkworm breeding amount in a manner of diluting by water. The solution is evenly sprayed on the surface of each folium mori, then fed to the silkworms after being evenly mixed, and respectively added to the silkworms at the fifth stage. The composition is simple in preparation step, and the application method is easy to operate, so that the prevention, control and application are convenient, easy and time-saving, the chlorfenapyr composition is small in dosage and is not frequent in usage count, prevention and treatment are just required at the fifth stage of silk and cocoon cultivation of the silkworms, and contribution to research and development of a novel drug for preventing and treating exorista sorbillans is made.

Description

technical field [0001] The present invention relates to a chlorfenapyr composition for controlling silkworm maggot flies, the invention also relates to a preparation method of a chlorfenapyr composition for controlling silkworm maggot flies, and the present invention also relates to a chlorfenapyr for preventing and controlling silkworm maggot flies The method for using the composition belongs to the field of chemical control of agricultural pests. Background technique [0002] Chlorfenapyr, the English name is Chlorfenapyr, the trade name is Suspending Agent, and the Chinese common name is Chlorfenapyr. The pure product is white or off-white oily powder. It is a new type of heterocyclic insecticide, Acaricide, nematicide. With the promulgation of the national highly toxic pesticide substitution policy and the improvement of people's awareness of environmental protection, as a representative of the recommended pesticide varieties for pest control of pollution-free agricultu...

Problems solved by technology

The third is serious harm. This year, silkworm farmers generally only have a production of about 30 kilograms. It is not easy to produce more than 35 kilograms. The loss rate of silkworm cocoons is as high as 15% to 30%.

However, since the beginning of this century, the masses have reported that the effect of using silkworm-killing flies has declined. In order to improve the control effect of silkworm-killing flies on silkworm-tracking flies, the dosage and frequency of medication have been continuously increased. Huang Ziran et al. Liao Fuping et al. carried out a preliminary test of the drug resistance of the silkworm chasing fly larvae to the silkworm fly. Feng Yuexiao et al.'s study "The influence of the silkworm chasing fly on the vitality of the silkworm chasing fly shows that some silkworm chasing flies are harmful to the insecticide. Silkworm flies develop resistance

[0006] The long-term use of killing silkworm flies, silkworm chasing flies have shown drug resistance, however, killing silkworms is still the main means of preventing and controlling the harm of silkworm chasing flies, and there has been no innovation in drug research so far
