Technical Field
The invention relates to the technical field of pesticides, in particular to a compound preparation containing florasulam herbicide and agricultural coconut oil synergist.
Background
The agricultural chemical has changeable use scene, and the plant has its own protecting mode, so that it has epidermis comprising epidermis cell, stomata, epidermis fur, etc. The epidermis is often surrounded by a waxy cuticle, the major constituent of which is lipids. Due to the existence of the horny layer, the absorption efficiency of the plant is greatly reduced after the pesticide is sprayed on the surface of the leaf. Pesticide is a process of diffusion through the stratum corneum. The surfactant can alter the penetration properties of the plant's cuticle and increase the ability of the pesticide to penetrate through the cuticle.
Similarly, the existing agricultural coconut oil synergist often focuses on reducing the surface tension and improving the effects of pesticide or fertilizer penetration and the like; however, also, excessively decreasing the surface tension increases the probability of bouncing for a spray-type dosage form; meanwhile, in order to improve the pesticide effect, the permeability of the pesticide is required too high in the market at present, so that more penetration and accumulation are often caused to plants, and pesticide residues are caused.
Aiming at the situation, the invention provides the compound preparation containing the florasulam herbicide and the agricultural coconut oil synergist, which can effectively and moderately stimulate the absorption of plants, does not excessively stimulate the plants to absorb pesticides, and simultaneously can effectively improve the pesticide effect.

As a preferred mode of the invention, the preparation method of the sulfonated alkyl glycoside comprises the following steps:
and (3) stirring and continuously reacting the C12C14 alkyl glycoside, sodium bisulphite accounting for 15% of the mass of the C12C14 alkyl glycoside and formaldehyde accounting for 5% of the mass of the C12C14 alkyl glycoside for 3 hours at 50-90 ℃, dehydrating and drying to obtain the sulfonated alkyl glycoside.
The raw materials for preparing the florasulam herbicide comprise florasulam and an auxiliary agent; the herbicide is prepared from the following raw materials in percentage by mass: 5% of florasulam and 95% of auxiliary agents.
Wherein the 95% adjuvant comprises: 2-10% of wetting dispersant, 0.1-5% of antifreezing agent, 0.5-5% of thickening agent, 0.1-1% of defoaming agent and the balance of water.

The application method of the compound preparation containing the florasulam herbicide and the agricultural coconut oil synergist is that 5 weight percent of the agricultural coconut oil synergist is added to the florasulam herbicide for mixed use when water is added.
The synergist provided by the invention can play a role in quick drug effect; simultaneously can stimulate the stomata of plants to open, and can be absorbed by drug effect. In addition, the invention can not blindly stimulate the increase of air holes, and can not only be used as a conventional surface activity to reduce the surface tension, but also stimulate hexokinase after subsequent decomposition, and stimulate the synthesis and closing of air holes because the invention selects the bio-based alkyl glycoside as a synergist. Meanwhile, after the matched herbicide is matched with the synergist, the effect is quick and long, and the possible reason is that the herbicide can stimulate guard cells to cause cytoplasmic acidification or alkalization so as to control the closing of stomata. Thereby effectively solving the problem of pesticide accumulation. Meanwhile, experiments show that the effect of the fluorine-containing herbicide is better, and the glycol and the methylamine alcohol in the matched antifreezing agent can be very beneficial to reducing the surface tension of the fluorine-containing herbicide on some surface three-dimensional, especially mastoid structures, so that the efficacy is very high.
The invention is further illustrated with reference to specific embodiments.
