Four major issues should be paid attention to in the development of special preparations for flight defense

From the perspective of pharmacy, flying defense belongs to the category of labor-saving preparations, which is very different from ordinary medicaments
.
As a very good and very good labor-saving pesticide application method, flying defense also needs to be combined with other labor-saving pesticide application methods
.
Compared with developed countries, the domestic research and development of special agents for flight defense is still very backward, and there are many defects in the management, specification, production, standards, efficacy, and performance of the agents
.
Professor Wu Xuemin of China Agricultural University believes that the entire flight control system is divided into three parts: plant protection strategy, selection of flight control agents, and improvement of application equipment
.
To do a good job in the prevention and control of diseases and insect pests, we must first have corresponding plant protection strategies.
To put it vividly, we must have a professional plant doctor.
Once the diseases and insect pests are determined, what kind of medicine should I choose? How to prevent it? The difference will be huge
.
Therefore, the plant protection strategy, the choice of medicament and the perfection of the application equipment are all indispensable
.
Speaking of medicaments, plant protection drones have developed rapidly in China in recent years, but there is still a lack of medicaments that can be used for flight defense, which has hindered the development of the flight defense industry to a certain extent
.
Enterprises need to pay attention to the following points when developing special preparations for flying defenses: First, the preparations must be able to adapt to low dilution multiples and have high stability after dilution
.
At present, most of the pharmaceuticals registered by domestic companies are usually diluted 500 to 1,000 times, which cannot meet the above conditions; second, for solid-liquid systems, the solid particle size should be small to avoid clogging the nozzle; third, the atomization effect should be good, and it can Effectively prevent droplet drift and volatilization
.
Speaking of this issue, the additives, tension, viscosity and other conditions of the medicine have a great influence on the atomization effect
.
To sum up, medicaments, preparations, and additives have a great impact on flying defenses; fourth, good interface performance, easy to deposit, wet, spread, penetrate and absorb
.
Nowadays, few domestic auxiliary companies specialize in flight control additives, and many of the auxiliary products purchased by companies are prepared for mass spray
.
In addition, the water spray and oil spray have no effect on the performance of the agent.

.
For example, when sprayed with water, the medicament is prone to increase in viscosity and precipitate crystals.
After spraying with oil, the physical and chemical properties of the medicament remain basically unchanged.
In addition, after spraying with water, the droplets are easy to evaporate and drift, and the oil is mixed After spraying, the droplets are not easy to evaporate; finally, oily additives need to be added after spraying with water, and there is no need to add special spraying additives for oil spraying
