How to prevent and cure flower black spot is effective.

In the period of planting flowers, the prevention and control of diseases is indispensable, and the occurrence of black spot has brought great harm to flowers.

In the prevention and control of black spot, we can spray 1000 times of carbendazim wettable powder as early as possible, and at the same time strengthen management, apply more phosphorus and potassium fertilizer, and improve the disease resistance of the plant. To control anthracnose, 120,160 times Bordeaux solution or 1000 times Dysen zinc wettable powder can be sprayed.

Friends who like to grow flowers should pay attention to the prevention of flower black spot disease in advance.

1. First of all, we should start with the source of infection, clean up the fallen leaves and remove the diseased leaves in time. In winter, it is necessary to strengthen the pruning of seriously diseased plants and remove the overwintering pathogens on diseased branches and leaves.

2, the potted plant arrangement should not be too dense, directly on the ground is easy to make the basin soil too wet because of the stagnant water on the ground, it is best to put it on the top of the stepped planting platform. It is necessary to change the watering method and time, slowly watering along the edge of the basin instead of spraying frequently. Do not water at night, because the wet leaves will be conducive to the invasion of bacteria.

3. Medication should be sprayed from the beginning of the new leaves in summer, usually every 7-10 days. The medicament can choose 500 times liquid (75%) of chlorothalonil wettable powder or 500 times liquid (50%) of carbendazim wettable powder, or 500 times liquid (80%) of Dysen zinc wettable powder or 100 times of Bordeaux solution (1) or 1000 times of methyl tropine (70%).
