Tomato pest control

Tomato pest control

Late blight

This disease is the most common and most harmful tomato disease, mainly manifesting itself on fruits and leaves. Once the disease occurs, the lesions will spread from the leaves to the main stem, and the tender stems of the plant will gradually rot and the branches and leaves above will die. For specific prevention and control methods, it is recommended to rotate crops with other plants that are not in the Solanaceae family for at least three years. During the disease season, diseased leaves and fruits should be picked off at any time. Avoid overwatering and prune promptly. When the disease starts, you can use 800 to 1000 times diluted 72% of the wettable powder of parathion.

Viral diseases

The symptoms of this disease are yellow top, clustering, curled leaves, etc. It usually occurs in a relatively dry and hot environment, especially when there are more aphids. You can choose disease-resistant hybrid varieties, or you can choose uninfected seeds for disinfection. When the disease first occurs, it is recommended to choose 1000 times of 40% powder for spraying for prevention and control. The powder must be soluble.

Cotton bollworm

This insect is the biggest pest of tomatoes. It can occur all year round and will eat the fruits and flowers of the plant, and even harm the buds, stems and leaves. The amount of pests can be reduced in time by pruning and topping the plants when cotton bollworms lay eggs. Alternatively, you can use 30% knock-down emulsion or 15% abamectin emulsion diluted 1000 to 1500 times during the hatching period and spray it when the sunlight is better.
