Why Do Pumpkins Rot at the Core? Detailed Explanation of Causes and Control Methods

The pumpkin originated in the Americas, in the region of Mexico, and was introduced to our country during the Ming Dynasty; it is now widely grown nationwide. It can be eaten and also used medicinally. Every part of the plant has different medicinal effects: the seeds have the effect of clearing heat and removing dampness, the vines have a heat-clearing effect, the fruit stalk has the effect of preventing miscarriage, and the roots can even treat toothache, so it can be said to be a treasure from top to bottom. However, many farmers often encounter core rot during cultivation, so what causes pumpkin core rot, and how should it be controlled? Let's take a look together with Qinnong Net.

1. Variety reasons

After many years of cultivation and selection, there are numerous pumpkin varieties. Some varieties are not suited to the local growing environment and climate when planted, so core rot and fruit rot occur.

Control methods: Choose varieties that grow vigorously, resist disease, have strong stress resistance and suit the local environment, such as Honey Ben Pumpkin, Yellow Wolf Pumpkin and Millstone Pumpkin. These three varieties are outstanding among pumpkins; they have strong adaptability, can grow in many environments, and also have strong disease and stress resistance, and are heat tolerant.

2. Improper management

Pumpkin is a warmth-loving short-day plant with fairly strong drought tolerance, but it is averse to waterlogging. If during cultivation it is exposed to intense direct sunlight for a long time, or if watering is improper or there is rainy weather, the soil becomes waterlogged, causing compaction and poor permeability. The roots take up too much water, which raises the pumpkin's water content, and then the soil receives strong light, so core rot and fruit rot are very likely to occur.

Control methods: When the pumpkin enters the fruit expansion stage, strictly control humidity and light. After watering, ventilate promptly to lower air humidity, and drain promptly after rainy weather. Normally, weed and loosen the soil promptly to increase soil permeability, promote root growth, enhance nutrient transport capacity, and let the fruit grow and develop rapidly.

3. Diseases

During cultivation, many diseases can cause pumpkin core rot and fruit rot, such as Phytophthora blight, viral disease, anthracnose and other diseases, all of which can cause pumpkin core rot and fruit rot.

Control methods: Before planting, treat the seeds with New High-Fat Film seed dressing, 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. When planting, use rational close planting, apply additional phosphorus and potassium fertilizer to improve the plant's disease resistance, observe promptly, and treat with chemicals promptly when disease is found.
