Abstract

The invention discloses a low-volume spray with hexythiazox and relates to pesticide. The low-volume spray comprises, by mass, 1-10% of hexythiazox, 5-15% of tea saponin and the balance water. During preparing, the water and the tea saponin are added into a blending kettle to be mixed evenly, the hexythiazox is added and fully disperses in the mixture of the water and the tea saponin, a sand mill is used for conducting milling, sampling is conducted, quality is detected, and filling and packaging are conducted. The water and the natural tea saponin serve as carriers, so the spray is safe to people and livestock and environmentally friendly and does not produce phytotoxicity to crops. The formula is simple, the water serves as the carrier, cost is low, and the cost performance is high. The amount of water for diluting the spray is small, and the spray is especially suitable for being sprayed in the dried and high mountainous water-deficient areas. The spray can be used for low-volume and ultralow-volume spraying, the work efficiency of the spray is higher than that of common spraying, and the labor cost is saved. The dripping loss of the pesticide is small, the pesticide utilization rate is high, and the environment pollution is reduced.

Description

technical field

[0001] The invention relates to pesticides, in particular to a low-capacity spray containing hexythiazox. 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 (667cm2), 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 ratio is greater than 1000 times, and the spraying volume per mu 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 effici...

Examples

Embodiment 11

[0025] Embodiment 1.1.0% hexythiazox low-volume spray

[0026] A. Formula: by mass percentage, hexythiazox 1.0%, tea saponin 15%, water 84.0%.

[0027] B. Process: Weigh 10kg of hexythiazox, 150kg of natural tea saponin, and 840kg of water respectively. First, add water into the mixing kettle, then add tea saponin, start the stirring device to fully mix; then, add hexythiazox and mix evenly, fully grind it with a sand mill, that is, process it into 1000kg of low-grade thiazox containing 1.0% Dosage spray.

[0028] C. Application: Dilute 100 times with water, spray with a low-volume sprayer, the spray volume per mu is 10L, the pesticide utilization rate is greater than about 60%, and the spray efficiency is 10 times that of the constant spray.

[0032] Embodiment 2, the preparation and application of 2% hexythiazox low-volume spray

[0033] A. Formula: by mass percentage, hexythiazox 2%, tea saponin 12%, water 86%.

[0034] B. Process: Weigh 20kg of hexythiazox, 120kg of natural tea saponin, and 860kg of water respectively. First, add water into the mixing kettle, then add tea saponin, start the stirring device to fully mix; then, add hexythiazox, mix well, and fully grind it with a sand mill, that is, process it into 1000kg containing 2% hexythiazox low volume spray.

[0035] C. Application: Dilute 80 times, spray with a low-capacity sprayer, the spray volume per mu is 8L, the pesticide utilization rate is about 65%, and the spray efficiency is 15 times that of the constant spray.

Embodiment 3

[0036] Embodiment 3, the preparation and application of 4% hexythiazox low-volume spray

[0037] A. Formula: by mass percentage, hexythiazox 4%, tea saponin 12%, water 84%.

[0038] B. Process: Weigh 40kg of hexythiazox, 120kg of natural tea saponin and 840kg of water respectively. First, add water into the mixing kettle, then add tea saponin, start the stirring device to fully mix; then, add hexythiazox, mix well, and fully grind it with a sand mill, that is, process it into 1000kg containing 4% hexythiazox low volume spray.

[0039] C. Application: Dilute 60 times, spray with a low-capacity sprayer, the spray volume per mu is 6L, the pesticide utilization rate is about 70%, and the spray efficiency is 20 times that of the constant spray.
