Systemic fungicides are very common and often heard, but specifically what is called systemic fungicides can not be explained by many people, the pesticide network Xiaobian to explain to you what is called systemic fungicide:
The systemic fungicide is simply a fungicide that can be absorbed into the plant through the leaves, stems and roots of the plant and transported to the site of action in the plant.
Systemic fungicide classification :
According to the running direction of the medicament, it can be divided into acropetal translocation and basipetal translocation.
Such fungicides themselves or their metabolites can inhibit the growth and development of infected pathogenic bacteria and protect plants from repeated infection by pathogenic bacteria, and have therapeutic effects after plant onset.
It can be sprayed directly, seeded or soil treated (filling, ditching, etc.). In actual use, because of its single action point, pathogenic bacteria are easy to produce drug resistance, and often mixed with other non-systemic fungicides with multiple points of action to delay the development of drug resistance. Some agents can be inhaled by plants, but they cannot be transported in the body. They are called osmotic or invasive, which is different from systemic action.
