Detailed Description
The formulation suitable for the plant protection unmanned aerial vehicle at the present stage is ultra-low volume liquid (UL), is a homogeneous phase liquid preparation directly used on ultra-low volume spraying devices, is also called ultra-low volume liquid, is actually oil agent, and is similar to missible oil by adding a plurality of auxiliary agents into the active ingredients and solvent components. It features high concentration, high efficiency, less water consumption, high adhesion and long acting period. The defects are that the solvent consumption is large, the corrosion to spray instruments is strong, the oil residue is difficult to clean, the fog drops are small, and the drifting phytotoxicity is easy to generate.
In order to solve the problems of easy drift, poor drug effect, poor adhesion and the like of the anti-flying spray, the anti-flying auxiliary agent becomes a main means for improving the drug effect and avoiding drift, but because of the compatibility and other problems of the formula and the auxiliary agent, the anti-flying auxiliary agent mostly follows the existing preparation and application principles, and is not combined in pesticide preparation products. Therefore, there is an urgent need for a glyphosate ultra-low volume liquid formulation that can be directly used in plant protection unmanned aerial vehicles, and that is resistant to drift, strong in adhesion, good in drug efficacy, and stable.
At present, the preparation of the glyphosate ultra-low volume liquid has the following difficulties:
firstly, the solubility of glyphosate raw medicine in organic solvent and water is poor, only salt prepared can be easily dissolved in water, so that the glyphosate raw medicine cannot be prepared into conventional ultralow-volume liquid, and the problems of poor adhesiveness, faster evaporation and serious drift of conventional liquid and other dosage forms cannot be effectively solved
Secondly, the existing synergists have very little effect on the glyphosate and all have certain defects, for example, the special synergists of the glyphosate on the existing market comprise aliphatic amine polyether, alkylphenol polyether surfactant, alkyl glycoside (APG), betaine and the like. The fatty amine polyoxyethylene ether has a stimulation effect on skin and eyes, has high fish toxicity, and is used for the condition that glyphosate-resistant crops often have yield reduction; the auxiliary agent containing alkylphenol polyoxyethylene groups is slow to degrade, and the alkylphenol as a final degradation product is more toxic, so that the auxiliary agent has potential harm to the environment; alkyl glycoside is the biggest glyphosate special auxiliary agent in the market at present, but the penetration promoting effect is weaker than that of tallow amine, and foam is easy to generate when packaged, so that the alkyl glycoside can only occupy part of low-end market; betaine is only effective for isopropylamine salts.
According to the application, the problem of dissolution of the glyphosate raw medicine is solved by using glyphosate salt and hydrolysis, water-based evaporation is avoided through the synergistic effect of the surfactant, the sedimentation agent and the like, so that the water-oil balance of the water-based part and the oil-based part of the sedimentation agent is achieved, and finally, the clear and stable glyphosate ultralow-volume liquid is obtained. The glyphosate ultra-low volume liquid is suitable for flight protection operation, and fills the blank that glyphosate preparation products are not suitable for flight protection operation.
Besides, the glyphosate ultralow-volume liquid has better anti-drift effect, good efficacy and adhesion, has obvious synergistic effect at the same concentration, can effectively avoid the remarkable improvement of the resistance of weeds to glyphosate in a short time, and has special effects on resistant weeds and erigeron breviscapus; meanwhile, the method has the advantages of good stability, short permeation time, long evaporation time and the like.

The implementation conditions adopted in the embodiments can be further adjusted according to different requirements of specific use, and the implementation conditions which are not noted are conventional conditions in the industry.
