Abstract

The invention discloses a dinotefuran-containing low-volume spray and relates to pesticides. The spray comprises the following raw materials in percentage by mass: 5-30% of dinotefuran, 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 dinotefuran is added to ensure that dinotefuran sufficiently disperses in the water and tea saponin mixed solution; milling with a sand mill is carried, 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 environment-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 dinotefuran. Background technique [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 the amount of liquid medicine sprayed per mu (667 square meters), spraying methods are often divided into constant spraying, low-volume spraying and ultra-low-volume spraying. [0003] 1. Constant spraying, pesticides are diluted with water, the dilution factor is greater than 1000 times, and the spraying volume per mu (667 square meters) 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 amo...
