Tomatoes, also known as tomatoes, have a delicious taste and are a common vegetable in our daily lives. However, during the cultivation process, tomatoes sometimes exhibit leaf curling, which affects their marketability and yield. Here's what you need to know about the causes and prevention measures for tomato leaf curl disease:
-
Low Temperature Leaf Curl: Tomatoes require a suitable temperature range of 16°C to 18°C at night and around 25°C during the day for optimal growth. Temperatures below 10°C can cause leaf curling due to cold damage. Solutions include temporarily increasing temperature with heaters or adding underground heating lines for protection during cold seasons.
-
High Temperature Leaf Curl: Temperatures above 30°C can slow tomato growth and lead to leaf curling due to excessive transpiration. Proper ventilation, shading, and application of protective solutions like Bi Hu can mitigate leaf curling symptoms.
-
Excessive Fertilization Leaf Curl: Over-fertilization can result in localized soil nutrient concentration, causing root burns and leaf margin curling. Control the amount of water-soluble fertilizer to reduce nutrient imbalance and leaf damage.
-
Herbicide Damage Leaf Curl: Nearby fields treated with herbicides can cause drifting, resulting in herbicide damage to tomato plants and leaf curling. Remedies include spraying Bi Hu solution to promote leaf expansion and enhancing plant growth with cultivation and fertilization.
-
Virus Infection Leaf Curl: Tomato plants infected with leaf curl virus exhibit symptoms such as stunting and upward leaf curling. Treatments involve foliar application of various antiviral agents to mitigate virus spread.
Tomato leaf curl disease is a common issue in tomato production, especially during hot summer and autumn seasons. It's important for growers to be vigilant and implement preventive measures.
