The pesticide forms commonly used in fruit trees include water solvents, water agents, sustained release agents and water-dispersible granules. Details are as follows:
First, the water solvent.
Spraying directly from the soluble drug . It is easy to process, easy to use, good in efficacy, easy to package, transport and store.
Second, the water agent The water-soluble original drug is directly dissolved in water to make a water agent, and diluted with water to the required concentration can be sprayed. The water agent is not resistant to storage, is easy to be hydrolyzed, has poor wettability, has weak adhesion, and has a long residual effect period.
3. Sustained release agent The preparation can be controlled to release slowly and reduce pollution and toxicity.
4. Water-dispersible granules Water-dispersible granules are obtained by re-granulating a wettable powder or suspension into water-dispersible granules. The key technology of processing is to prevent the particles from re-flocating into coarse particles during the granulation process or during storage of the finished product. Therefore, an additive called a release agent is used in the formulation, which can separate the particles. Come. This dosage form requires a low rate of shedding and no powder is present in the product. The dosage form has good fluidity, is easy to use, has no dust flying, and is safe.
Only by grasping the properties of pesticide formulations can we use pesticides more prepared. For more pesticide information, please pay attention to China Pesticide Network !
