Problems solved by technology

The artificially synthesized brassinolide has high activity, which can be absorbed by the leaves, stems and roots of plants, and then transmitted to the site of action. Some believe that it can increase the activity of RNA polymerase, increase the content of RNA and DNA, and some It is believed that it can increase the potential difference of the cell membrane and the activity of ATPase, and some believe that it can strengthen the effect of auxin. There is no unified view on the mechanism of action.

Embodiment 1

[0011] Embodiment 1: grape yield increase test

[0012] By measuring the yield per mu of grapes treated with the chemical agent, comparing the yield increase rate of the mixed agent and the single agent, it is judged whether the mixed agent has a synergistic effect.

[0013] Dilute 95.4% Cholinechloride and 0.1% Brassinolide with acetone and Tween-80 respectively to make 1.6 μg / mL mother liquor, and use the mother liquor to prepare Thidizuron and Brassinolide Orcinolactone mixture test. The specific data of the test results are shown in Table 1.

[0014] Table 1. Effect test of thiadizuron and brassinolide on grape yield

[0015] deal with

[0016] Through the indoor potted grape yield measurement test, it was found that thiadiuron and brassinolide compounded in different proportions had a synergistic effect on the increase in grape yield, and the effect on grape yield increase was obvious. It can be seen that the combination of thiadizuron and brassinolide has a...

Embodiment 2

[0017] Example 2: 0.5% thiadizuron brassinolide aqueous solution

[0018]

[0019] After stirring and dissolving the above active ingredients with a solvent, other additives are added, fully stirred and mixed uniformly, and 0.5% thiadizuron-brassinolide aqueous solution can be prepared.

Embodiment 3

[0020] Embodiment 3: field efficacy test

[0021] Adopt 0.5% thiadizuron brassinolide aqueous solution (embodiment 2) to be used for improving grape yield, test site is Nanning City, Guangxi, test time is June 2015, select the better grape field block of water and fertilizer field, adopt by mechanical spraying. The 0.004% brassinolide aqueous solution 2000 times was used as the control drug, and the above-mentioned 0.5% thiadizuron-brassinolide aqueous solution 750 times was used for the test treatment. The grapes were sprayed for fruiting, sprayed twice, and the growth of grape ears was investigated 30 days after spraying. The control effect was calculated in strict accordance with the calculation method stipulated in the national standard of the People's Republic of China "Pesticide Efficacy Field Test Guidelines" 60 days after spraying. After 60 days of the above drugs, the corrected yield increase rates were 3.3% and 8.6%, respectively. Tests have shown that 0.5% thiadiz...

Abstract

The invention relates to a pesticide composition containing thidiazuron and brassinolide. The composition comprises effective components, namely 0.01 to 80 percent of thidiazuron and 0.01 to 10 percent of brassinolide in percent by weight. The pesticide composition can be prepared into water aqua during actual application. The pesticide composition can be used for grape adjustment growth, and is a formula of a plant growth adjustor worthy of being popularized.

Description

technical field [0001] The invention relates to a pesticide composition, the active ingredients of which include thidiazuron and brassinolide, which are mainly used for regulating the growth of grapes. Background technique [0002] Thidiazuron is a plant photosynthesis accelerator, which has obvious effects on increasing yield. Spraying grapes in the young fruit stage can promote the growth of fruit grains and more grains, and spraying in the expansion stage can speed up the expansion speed, the grains are full, and the single grain weight increases. It can also be used to increase the yield of corn, sugarcane, sweet potato, grape, radish, onion, cotton, tobacco, vegetable, grape, mango, etc., and the effect is stable under different climate and ecological environment conditions. [0003] Brassinolide is one of the steroidal compounds with higher biological activity, and they are widely present in plants. In each stage of plant growth and development, it can not only promo...
