Water dispersion granule containing flumetralin and uniconazole

Abstract

The invention discloses a water dispersion granule containing flumetralin and uniconazole. The water dispersion granule comprises, in weight percentage, 1%-60% of flumetralin, 0.5%-8% of uniconazole, 0.5%-2% of wetting agents, 0.5%-2% of dispersing agents, 1%-5% of adsorbing agents, 2.5%-5% of disintegrating agents, 1%-5% of stabilizing agents and the rest fillers. The water dispersion granule is environmentally friendly, low in cost and safe for trees and fruits, summer shoot control effects are excellent, and duration of pesticide effects is long.

Description

[0001] Technical field: [0002] The invention belongs to the field of plant growth regulators, and in particular relates to a water-dispersible granule mainly used in tobacco bud suppression, citrus shoot control, etc. [0003] technical background: [0004] Summer in the south is hot and rainy, and citrus shoots grow vigorously in summer, which will inevitably consume a large amount of nutrients in the tree body, and there will be a situation where the shoots and fruits compete for fertilizer. When the tree body cannot meet the nutrients needed for fruit growth and development, a large amount of physiological fruit drop will occur; At the same time, the occurrence and spread of citrus huanglongbing is also mainly concentrated on the new shoots of citrus. At present, there is no effective pesticide to kill the occurrence of citrus huanglongbing. , the control of summer shoots can not only reduce the second physiological fruit drop rate, but also prevent Huanglongbing and achie...

Problems solved by technology

[0004] Summer in the south is hot and rainy, and citrus shoots grow vigorously in summer, which will inevitably consume a large amount of nutrients in the tree body, and there will be a situation where the shoots and fruits compete for fertilizer. When the tree body cannot meet the nutrients needed for fruit growth and development, a large amount of physiological fruit drop will occur; At the same time, the occurrence and spread of citrus huanglongbing is also mainly concentrated on the new shoots of citrus. At present, there is no effective pesticide to kill the occurrence of citrus huanglongbing. , controlling summer shoots can not only reduce the second physiological fruit drop rate, but also prevent Huanglongbing disease, and achieve the effect of increasing production and stabilizing harvest

Paclobutrazol is selected as the conventional tip control element, and the concentration is about 500 ppm. It is required to effectively control the new shoots below 3cm, and the effective control time is 25 to 35 days. Although it can effectively control summer shoots, it is easy to cause stiff leaves, Improper use of phytotoxicity such as flower skin and fruit will even cause damage to the tree, resulting in a serious decline in the amount of fruit in the second physiological fruit drop period, and at the same time will affect the quality of citrus
