Cyhalothrin-containing low-volume spray

Abstract

The invention discloses a cyhalothrin-containing low-volume spray and relates to pesticides. The spray comprises the following raw materials in percentage by mass: 2.5-30% of cyhalothrin, 5-15% of tea saponin and the balance of water. During preparation, water and tea saponin are added into a blending kettle for uniform mixing, and then cyhalothrin is added to ensure that cyhalothrin sufficiently disperses in the water and tea saponin mixed solution; milling with a sand mill is carried out, sampling for qualification inspection is performed, and filling package is carried out. Water and tea saponin are taken as carriers, so that the spray is safe to human and animals, low in phytotoxicity to crops, safe and environmentally friendly; the formula is simple and water is taken as the carrier, so that the cost is low and the cost performance is high; the consumption of water for pesticide dilution is low, so that the spray is particularly suitable for arid regions and water-deficient high mountain regions; the spray can be applied to low-volume and super-low-volume spraying; compared with the normal-volume spraying, the low-volume and super-low-volume spraying are higher in working efficiency and lower in labor cost; the liquid pesticide dropping loss is low and the pesticide utilization ratio is high, so that the environmental pollution is reduced.

Description

technical field

[0001] The invention relates to pesticides, in particular to a low-capacity spray containing cyhalothrin. technical background

[0002] The spraying method is the most common application method for the drug control of crop diseases and insect pests and sanitary pests, that is, a certain amount of pesticide and an appropriate amount of water or oil are used to prepare a liquid medicine, and the liquid medicine is sprayed into mist droplets with a spraying device. According to each mu (667m 2 ) how much liquid medicine to spray, the spray method is often divided into constant spray, low-volume spray and ultra-low-volume spray.

[0003] 1. Constant spraying, the pesticide is diluted with water, and the dilution factor is greater than 1000 times, and each mu (667m 2 ) The spray volume is 45-60L, which is the conventional spraying method in the field of plant protection in my country at this stage. This spraying method has a large amount of spraying, low work e...
