Let's take a look together!
Causes of Pumpkin Heart Rot and Prevention and Control Methods
1. Variety reasons
Growing pumpkins is very convenient now, and there are more and more varieties to choose from, but everyone often overlooks one problem: some varieties are actually not suitable for widespread cultivation in every region, and this is the main reason leading to pumpkin heart rot.
Prevention and control methods: Choose varieties with strong growth, disease resistance, and strong stress resistance that suit the local environment, such as Miben pumpkin, Huanglang pumpkin, and Mopan pumpkin. These three varieties are outstanding among pumpkins; they have strong adaptability, can grow in many environments, and also have strong disease resistance and stress resistance, and are heat tolerant.
2. Improper management
Pumpkin is a warmth-loving short-day plant with relatively strong drought tolerance, but it is sensitive to waterlogging. If during cultivation it is exposed to intense direct sunlight for a long time, or if watering is improper or there are rainy days, causing excessive water accumulation in the soil, soil compaction, and poor permeability, the root system absorbs too much water, leading to increased water content in the pumpkin. Then, when the soil receives strong light, heart rot and fruit rot are very likely to occur.
Prevention and control methods: When pumpkins enter the fruit expansion stage, humidity and light must be strictly controlled. After watering, ventilate promptly to reduce air humidity, and after rainy days, drain water promptly. In daily work, everyone should pay more attention to field management and frequently go to the field to look around. If there are weeds, remove them quickly to maintain a good growing environment. In this way, nutrients can also reach the pumpkin root system through loose soil.
3. Diseases and insect pests
During cultivation, many diseases can cause pumpkin heart rot and fruit rot, such as phytophthora blight, viral disease, and anthracnose, all of which can cause pumpkin heart rot and fruit rot.
Prevention and control methods: Before planting, treat seeds by mixing with Xin Gao Zhi Mo, which can eliminate pathogens carried on the seed surface. Deep plow and sun-bleach the soil to eliminate pathogens in the soil, so that pathogen infection can be blocked at the source. During planting, use rational close planting, apply additional phosphorus and potassium fertilizer to improve the plant's disease resistance, observe promptly, and when disease is found, treat it promptly with chemicals.
