Most chemical compounds are found in plant leaves and other parts.
The second piece
Used in suppression. When fungicide and bactericidal chemical compounds are sprayed on the gaseous part of the plant in liquid or crushed state, it fights various fungi and bacteria or destroys the pathogens in the germ. Bactericidal agents inhibit the growth of bacteria or cause their death. Generally, more benefits are obtained by using sprays instead of crushing bacteria and fungicides. But it is reasonable to use them in the rainy season. This is because during the rainy season, the wet plant sticks to the crust quite well. Depending on the nature of the plant rage, the duration and rate of rainfall and the different seasons of the year, the aerial parts of the rage-infected plants should be sprayed every 7 to 14 days and depending on all these factors, spraying should be done twice or 3 to 15 times in each season. Among the chemical compounds used for spraying and crushing, copper, sulfur, mercury and zinc are the major compounds.
