First, sunny management
The general situation of tomato rotten fruit is caused by pathological infection caused by poor weather or improper time during management. Therefore, it is required that plant management of tomatoes must be carried out in fine weather.
Second, the removal of the source of law
After the tomato is infected with the pathogen, the branches and leaves are more obvious. When there are brown spots on the branches and leaves, this is the initial stage of the infection. It is necessary to remove and destroy the diseased leaves and leaves in time, and remove the residual leaves and decaying leaves on the ground in time to concentrate on Outside the park, burn it or dig it. Prevent the spread of the source.
Third, the application of pesticide control
When the weather is continuous and rainy, and the humidity of the air is high, the tomato is most susceptible to infection, and it is necessary to carry out drug control. Soft rot can be sprayed with 70% dikesone 1000 times liquid, spray once every 8~10 days; brown spoilage disease is sprayed with 25% of toxic mycelium 800~1000 times, spray once every 7 days, Spray even 2~3 times; anthracnose is sprayed with 80% anthrax hydrazine WP 800 times or 50% carbendazim WP 500 times, spray once every 8~10 days, even spray 2 times.

The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
