<p>Most people have probably eaten strawberries. They are very sweet and full of water, and many people grow them. Because growing strawberries offers great economic benefits, and the market price of strawberries is relatively high among fruits, the income can be quite considerable if they are grown properly. But many fruit growers find that strawberries often get sick during cultivation, so what are the common strawberry diseases? How should they be controlled? Let's take a look below!</p>
<p></p>
<p><strong>1. Leaf spot</strong></p>
<p>Disease characteristics: Leaf spot can occur on any organ of the strawberry plant. It mainly harms the leaves. After the leaves are infected, darker spots appear on the surface, and the spots gradually expand to form patches of varying sizes with darker edges. The middle of the patch is white and develops many small black dots.</p>
<p>Control methods: Promptly remove the infected parts, such as diseased leaves and diseased fruit, and dispose of them far away from the orchard. After infection, chlorothalonil wettable powder can be sprayed for control, once every 7-10 days.</p>
<p></p>
<p><strong>2. Powdery mildew</strong></p>
<p>Disease characteristics: The main site of powdery mildew infection is also the leaves, and it occasionally harms other organs of the plant as well. After the leaves are infected, white mold appears, and the mold layer takes on the shape of a spoon. After flowers are infected, the disease occurs on the buds and petals, with darker color, affecting flowering; in severe cases, the plant cannot bloom, the fruit develops poorly, expansion is hindered, fruit quality is reduced, and it loses commercial value.</p>
<p>Control methods: Strengthen orchard management. After infection, spray Bordeaux mixture and lime sulfur mixture around the plants. At harvest, cut off all the leaves, then spray the whole orchard with solutions such as thiophanate-methyl for control.</p>
<p></p>
<p><strong>3. Gray mold</strong></p>
<p>Disease characteristics: The peak period of gray mold is during the plant's flowering stage. Like leaf spot, it harms most organs of the plant. It mainly occurs on the fruit. After the fruit is infected, many brown spots appear, and the spots slowly expand and then join together to form a large patch, causing the fruit to rot and soften, with rotten and fallen fruit, greatly affecting yield.</p>
<p>Control methods: Carefully observe the plant's growth progress. Before the flowering stage arrives, spray agents such as carbendazim wettable powder for prevention. Manage the orchard well, drain and irrigate in a timely manner, and improve orchard ventilation.</p>
<p></p>
<p><strong>4. Root rot</strong></p>
<p>Disease characteristics: Root rot mainly occurs on the leaves. When the leaves are infected, it mainly starts from the lower part and then gradually spreads to the upper leaves, with the leaf edges becoming darker. After the leaves are infected, they slowly wilt and eventually die. As the leaves wither, the plant also slowly changes color and eventually rots, affecting nutrient absorption and transport and causing great harm to plant growth.</p>
<p>Control methods: When transplanting strawberries, spray asparagus green powder on the beds. After spraying, cover with an appropriate amount of soil, then transplant. This reduces or even eliminates pathogens in the soil, reducing pathogens and lowering the disease incidence.</p>
<p></p>
<p>The four diseases above are relatively common in strawberry cultivation and can have a great impact on plant growth, not only reducing yield but, in severe cases, leading to total crop loss. Therefore, when planting, we must pay attention to strengthening orchard management and promptly remove fallen leaves and fruit and diseased leaves and fruit from the orchard. Prevent re-infection. That is all for today's introduction. This article is for reference only, and we hope it is helpful to everyone.</p>
Most people have probably eaten strawberries; they are very sweet and full of juice, and many people grow them. Because growing strawberries offers great economic benefits, the market price of strawberries is relatively high among fruits, and with proper cultivation the income can be very considerable. But many fruit growers find that strawberries often get sick during cultivation. So what are the common diseases of strawberries? And how should they be prevented and controlled? Let's take a look below!
1. Leaf spot
Disease characteristics: Leaf spot can develop on any organ of the strawberry plant. It mainly damages the leaves; after the leaves are affected, darker-colored spots appear on the surface, and the spots gradually expand to form patches of different sizes, with the edges of the patches being darker in color. The center of the patch is white, and many small black dots appear.
Prevention and control methods: Promptly remove the affected parts, such as diseased leaves and diseased fruit, and dispose of them far away from the orchard. After the disease occurs, chlorothalonil wettable powder can be sprayed for prevention and control, once every 7-10 days.
2. Powdery mildew
Disease characteristics: The main site of powdery mildew infection is also the leaves, and it occasionally damages other organs of the plant as well. After the leaves are affected, a white mold layer appears, and the mold layer takes on the shape of a spoon. After flowers are infected, the disease appears on the flower buds and petals, with a darker color, affecting flowering; in severe cases they cannot bloom, the fruit develops poorly, expansion is hindered, fruit quality is reduced, and it loses market value.
Prevention and control methods: Strengthen orchard management; after the disease occurs, spray Bordeaux mixture and lime sulfur mixture around the plants. At harvest, cut off all the leaves, then spray the whole orchard with solutions such as thiophanate-methyl for prevention and control.
3. Gray mold
Disease characteristics: The peak period of gray mold is during the plant's flowering stage, and like leaf spot, it harms most of the plant's organs. It mainly occurs on the fruit; after the fruit is affected, many brown spots appear, and the spots slowly expand and then join together to form a very large patch, causing the fruit to rot and soften, with rotten and dropped fruit, greatly affecting yield.
Prevention and control methods: Carefully observe the plant's growth progress; before the flowering stage arrives, spray agents such as carbendazim wettable powder for prevention. Do a good job in orchard management, drain and irrigate promptly, and enhance orchard ventilation.
4. Root rot
Disease characteristics: Root rot mainly occurs on the leaves. When the leaves are affected, it starts mainly from the lower part and then gradually spreads to the upper leaves, with the leaf edges deepening in color. After the leaves are affected, they slowly wilt and finally die. As the leaves wither, the plant also gradually changes color and eventually rots as well, affecting nutrient absorption and transport and causing great harm to plant growth.
Prevention and control methods: When transplanting strawberries, spray asparagus green powder on the beds, then cover with an appropriate amount of soil before transplanting, so as to reduce or even eliminate pathogens in the soil, reduce the sources of infection, and lower the disease incidence.
The four diseases above are relatively common in strawberry cultivation. They have a great impact on plant growth and not only reduce yield but, in severe cases, can lead to total crop failure. Therefore, when planting, we must pay attention to strengthening orchard management and promptly remove fallen leaves and fruit, as well as diseased leaves and fruit, from the orchard. Prevent re-infection. That is all for today's introduction. This article is for reference only, and we hope it is helpful to everyone.
