The latest common diseases of strawberries and their control

Most people should have eaten strawberries. They are very sweet and well hydrated, and many people grow strawberries. Because growing strawberries has great economic benefits, the market price of strawberries is relatively high in fruits, and its income is very considerable if it is planted properly. But many fruit growers will find that strawberries often get sick when they are growing, so what are the common diseases of strawberries? How to prevent and cure it? Let's take a look at it.

1. Leaf spot

Disease characteristics: leaf spot disease can occur in any organ of strawberry plant. The main harm to the leaves, the leaves will appear darker spots on the surface, the spots will gradually expand to form patches of different sizes, and the color of the edge of the patch is darker. The plaque is white in the middle, and there are many small black spots.

Prevention and treatment: remove the affected parts in time, such as diseased leaves and diseased fruits, and deal with them far away from the orchard. After the onset of the disease, chlorothalonil wettable powder can be used for spray control, once every 7-10 days.

2. Powdery mildew

Disease characteristics: powdery mildew mainly occurs in leaves and occasionally harms other organs of the plant. After the disease of the leaves, there will be a white mildew layer, which shows the shape of a spoon. Flowers will become ill on the flower buds and petals after infection, the color is dark, affect flowering, seriously can not blossom, fruit development is poor, expansion is hindered, reduce fruit quality, lose commercial value.

Prevention and control methods: strengthen orchard management and spray Bubaomeite sulfur mixture around the plant after the disease. After harvesting, all the leaves were cut off, and then the whole garden was sprayed with methyl topiramate and other solutions for control.

3. Grey mold

Disease characteristics: the high incidence period of Botrytis cinerea is at the flowering stage of the plant, which, like leaf spot, can harm most organs of the plant. Mainly occurs in the fruit, there will be many brown spots after the disease, the spots will slowly expand, and then connected to form a large patch, resulting in fruit decay and softening, rotten fruit, which has a great impact on the yield.

Control methods: carefully observe the plant growth process, before the arrival of flowering, the use of carbendazim wettable powder and other agents for prevention. Do a good job in orchard management, timely drainage and irrigation, enhance orchard permeability.

4. Root rot

Disease characteristics: root rot mainly occurs on leaves. When the disease occurs, the leaf mainly starts from the lower part, and then gradually spreads to the upper leaf, and the color of the leaf edge deepens. After the disease, the leaves will slowly wither and eventually die. The pillars will also slowly change color with the withering of the leaves, and eventually will rot, affecting the absorption and transport of nutrients, resulting in greater harm to the growth of plants.

Control methods: when transplanting strawberries, spray asparagus green powder on the border, cover the right amount of soil after spraying, and then transplant, so as to reduce or even eliminate the bacteria in the soil, reduce the pathogen and reduce the incidence of disease.

The above four diseases are common in strawberry planting, which will have a great impact on plant growth, not to mention reducing yield, which will lead to extinction in serious cases. Therefore, when we plant, we must pay attention to strengthen the management of the orchard and remove the fallen leaves and diseased fruits out of the orchard in time. To prevent further infection.
