Cucumber seeds infected with pathogens such as fusarium wilt, anthracnose, bacterial blight, and powdery mildew can be treated to disinfect their surfaces before planting. This helps improve germination rates and reduce disease risks in the early stages of growth.
First, a warm water soaking method is commonly used. Dry cucumber seeds are soaked in warm water at 50°C to 60°C for approximately 10 minutes. During this time, it's important to continuously stir the seeds to ensure even exposure. Afterward, the temperature should be gradually reduced to 28°C to 30°C, and the seeds are left to soak for about 46 hours. Once this process is complete, the seeds should be drained and allowed to sprout before being sown.
Another effective method is chemical disinfection. A 0.1% solution of carbendazim hydrochloride is used to soak the seeds for one hour. Afterward, they are thoroughly rinsed with clean water and then soaked in fresh water for 4 hours to prepare them for germination.
A third approach involves using a seed coating agent. These coatings contain fungicides and essential micronutrients that not only help prevent fungal infections but also enhance seed quality. The coated seeds show improved germination rates and stronger early growth. This treatment allows the seeds to be directly soaked and germinated or even sown directly into the soil without additional preparation. Using a seed film is a convenient and efficient way to protect seeds from diseases while promoting better plant development.
