Problems solved by technology

Due to the large content range of the functional agent Thidiazuron in this product, the defoliation effect is not stable
And this product is emulsified formulation, containing 30%-80% organic solvent, not only the cost is very high but also cause farmland environmental pollution after leaving soil

Embodiment 1

[0012] Example 1. Cotton defoliant of the present invention, each component and its weight percent constitute as follows: 50% of thiadizuron, 15% of GY-D0, 43% of GY-D0, 3% of polycondensed naphthalene sulfonate, 1% of alkyl naphthalene salt, Xanthan gum 0.1%, simethicone 0.3%, ethylene glycol 5%, water balance.

[0013] Its preparation process is as follows: adding thiadizuron, GY-D01, GY-D04, polycondensed naphthalene sulfonate, and alkyl naphthalene salt in accordance with the above weight percentages into water, grinding for 1 hour with a wet pulverizer, and then adding yellow Raw gum, defoamer, ethylene glycol, and the rest of water are stirred, and then coarsely ground and finely ground, so that the particle size is less than 4 microns, and the finished product can be obtained.

Embodiment 2

[0014] Example 2. Cotton defoliant of the present invention, each component and weight percentage thereof are constituted as: 52% thiadizuron, GY-D016%, GY-D043%, polycondensed naphthalene sulfonate 2%, alkyl naphthalene salt 0.7%, Xanthan gum 0.1%, simethicone 0.3, ethylene glycol 5%, water balance. Its preparation technology method is with embodiment 1.

[0015] The 2-year field test demonstration using the product of Example 1 of the present invention shows that the product can effectively promote cotton boll opening. Compared with the clearing (50% thiadiuron wettable powder) produced by Jiangsu Ruibang Pesticide Co., Ltd., and the toturon (36% thiadiuron + 18% diuron suspending agent) produced by Bayer, Germany, the cumulative boll opening The rate is 8%-10% higher. Mu input cost savings of more than 10%. In addition, the hanging leaves of cotton plants are relatively light, which reduces the difficulty of cleaning after harvesting.

Abstract

The invention provides a thidiazuron suspension cotton defoliating agent, which comprises the following components in percentage by weight: 47.5 to 52.5 percent of thidiazuron, 3 to 6 percent of GY-D01, 1 to 3 percent of GY-D04, 2 to 3.5 percent of naphthalene sulfonate polycondensate, 0.4 to 1.2 percent of alkyl naphthalene acid salt, 0.05 to 0.15 percent of xanthan gum, 0.3 to 4.0 percent of dimethyl silicon oil, 4.5 to 5.5 percent of ethylene glycol and the balance of water. The thidiazuron suspension cotton defoliating agent has the advantages of small particular size, large active surface area, high seepage force, no dust during medicine preparation, low cost, high medicine effect, cold and freezing resistance and the like. The thidiazuron suspension cotton defoliating agent has the advantages of both wettable powder and missible oil, can be wetted by water, has high suspension property after being diluted by water, and can be directly prepared into spray liquid to be used. The thidiazuron suspension cotton defoliating agent can effectively prevent cotton from remaining green when it is due to become yellow and ripe and delaying ripping, promote cotton bolls to open, improve flower rate before frosting, increase yield and improve cotton quality, and is an ideal medicinal agent for machine picking and manual picking.

Description

1. Technical field [0001] The invention relates to a cotton defoliation treatment technology, in particular to a cotton defoliation agent for machine-picked cotton. 2. Background technology [0002] Cotton is an important economic crop in my country. With the continuous improvement of cotton planting level and steady increase in output, the workload of cotton harvesting has gradually increased. However, due to rising labor costs and a shortage of flower-picking laborers, the large-scale and intensive cultivation of cotton has been greatly restricted. Mechanized harvesting is the only way to solve this problem. Especially in Xinjiang and other provinces and regions with large per capita management area and scarce labor force, it is more realistic to realize cotton mechanical harvesting. [0003] Cotton defoliation is a key link in machine-picked cotton, and the quality of defoliation is related to the quality of harvested cotton products. The implementation of manual defo...
