Causes of grape rotten fruit and its prevention methods

Last year, when we planted grapes, a significant portion of our vineyards suffered from severe fruit rot. As the disease spread, many growers turned to heavy applications of fungicides, but the results were disappointing, leading to major losses for grape farmers. So, what caused this widespread rot, and how can it be prevented? One of the main reasons is environmental conditions. Most of the pathogens that cause grape diseases—such as downy mildew, white rot, and gray mold—thrive in wet, humid conditions. During rainy seasons, these diseases tend to occur more frequently, causing serious damage and leading to rotten fruit. Another factor is poor vine management. Overly dense foliage, excessive clusters, and inadequate air circulation create an ideal environment for pests and diseases to flourish. This lack of ventilation and sunlight increases the risk of infections, ultimately resulting in fruit rot. Nutritional imbalances also play a role. When vines are not properly fertilized, especially with a deficiency in phosphorus, potassium, and essential micronutrients, their resistance to pests and diseases weakens. Excessive nitrogen can further exacerbate the problem, making the plants more susceptible to infection and leading to fruit rot. To address these issues, several control methods can be implemented: 1. **Selecting disease-resistant grape varieties** is a crucial first step. For example, the "Kantai" variety is known for its strong resistance to downy mildew and powdery mildew, while other large-berried types offer good protection against black rot and anthracnose. 2. **Prevention should be the priority** in pest and disease control. Early intervention is key. At the initial signs of disease, you can use 50% Triflumuron WP diluted at 500 times, 70% Thiophanate-Methyl WP at 600 times, or 50% Carbendazim wettable powder at 800 times. Apply these treatments every 7–10 days, repeating 2–5 times depending on the severity. After heavy rains, make sure to spray promptly to prevent further spread. 3. **Insect control** involves targeting specific pests like thrips, two-spotted leafhoppers, and grape tiger moths. Thrips and leafhoppers can be managed with Imidacloprid diluted at 2000–3000 times, while grape tiger moths can be controlled using Cypermethrin at 2000 times or Avermectin at 4000–5000 times. 4. **Fruit bagging** is an effective method to reduce pest damage and prevent cracking and rotting. Bag the grapes immediately after the fruit set, and apply a disinfectant insecticide before sealing. Remove the bags 1–2 weeks before harvest to allow proper color development. 5. **Summer pruning** helps improve air circulation and light penetration. Remove excess shoots and leggy branches, and perform careful pruning to balance vegetative and reproductive growth. Retain only one full shoot per node on the mother vine, and remove all other lateral shoots and buds. About 5–7 days before flowering, pinch back the top 4–5 leaves above the inflorescence on the fruiting shoots. Also, thin out flowers and fruits during the flowering and fruit enlargement stages to avoid overloading the vines and improve fruit quality. 6. **Soil testing and balanced fertilization** are essential for long-term health. In the fall, apply organic compost, and in the following spring and summer, supplement with appropriate fertilizers and bio-organic materials based on soil test results. This ensures the soil remains rich in organic matter, loose, and fertile, supporting healthy root growth and overall plant vitality. By combining these strategies, grape growers can significantly reduce fruit rot and ensure better yields and quality. Prevention is always better than cure, and taking proactive steps now can save time, money, and resources in the long run.

Loss Weight

The scientific name of MCT is called medium chain fatty acids, which naturally exist in breast milk. Everything in breast milk is the essence. Its unique structure can decompose energy rapidly and efficiently in the liver, and MCT has the advantage of being rapidly digested and absorbed. It does not need hydrolysis of pancreatic lipase and does not involve lymphatic system. The unique metabolic pathway determines the positive effect of MCT on weight loss. In other words, if you eat MCT, even if you don't eat carbohydrates, your body will have a significant sense of satiety.


1. Appetite suppression:

Increase satiety, delay gastric emptying time, and directly affect the central nervous system

2. Inhibit digestion and absorption:

Inhibit the digestion and absorption of carbohydrates: inhibit the function of related catabolic enzymes and delay the speed of absorption

3. Inhibit the digestion and absorption of oil:

Inhibit the effect of lipolytic enzymes, avoid the contact between oil and lipolytic enzymes, and delay the absorption of fatty acids

4. Promote metabolism:

Increase energy consumption, increase fat oxidation, reduce fat formation
