First, fungal diseases:
Familial melons have the following facultative diseases: cucumber blight, cucumber anthracnose, watermelon anthracnose, melon anthracnose, cucumber wilt, cucumber blight, cucumber scab, pumpkin scab, and melon white peony. Most of these diseases are mycelium latent in the seeds, but also the appearance of seed attachment with conidia or sclerotia. The methods for disinfecting the seeds of the above diseases are:
1. Warm soaking: Seeds are soaked in warm water at 55°C for 15 minutes (minutes), then cooled with cold water, germinated and sowed.
2. Pharmaceutical soaking:
(1) Formalin soaking: Use 40% formalin 100 times soaking for 30 minutes, wash with water after soaking, then sowing or air dry.
(2) Carbendazim or Precore soaking: Use 50% Carbendazim 500 times soaking for 1 hour (hours), or 72.2% Preclosures 800 times soaking for 0.5 hours.
(3) Seed ammonium soaking: Soaking for 1 h with 500% solution of 50% dexamethasone.
(4) Imidazolium Hydrochloride Soaking: Soaking with 100 imidazole hydrochloride 500 times for 1 to 2 hours.
(5) Soaking with bleaching powder: To control cucumber wilt disease, the seeds can be soaked in a 2% to 3% bleach solution for 30 to 60 minutes. The soaked seeds are washed with water and then air-dried.
3. Chemical seed dressing:
(1) Fumei Double Seed Dressing: 50% thiram can be used to control cucumber blight and seed dressing is applied at a seed weight of 0.4%.
(2) Green Hunter No. 2 WP: Seed dressing with 4 to 5 g per kilogram of melon seed can effectively prevent fungal diseases lurking on seeds.
Second, bacterial diseases:
The common method is cucumber bacterial keratoses. The method of disinfecting seeds of the disease is:
1. Warm soup soaking: specific methods with cucumber anthracnose and other fungal diseases, this method has a good effect on the control of cucumber bacterial angular spot.
(1) Formalin soaking: Soaking with 150 times 40% formalin for 1.5 hours, soaking the seeds, washing them thoroughly with water, and air-drying.
(2) Streptomycin sulfate soaking: soaking for 2 hours with 1,000,000 units of streptomycin sulfate 500 times, rinse and germination.
Third, virus disease:
Common melon virus diseases include: cucumber mosaic disease, watermelon, gourd and melon and other virus diseases. These seed disinfection methods are:
1. Warm soaking: For cucumber mosaic disease, the seeds can be soaked in hot water at 60-62°C for 10 minutes or immersed in hot water at 55°C for 40 minutes. Immediately after the time, the seeds are put into cold water to cool, and then sown after drying. Good control effect.
2. Seed soaking: Green leaf mosaic virus carried by melon seeds such as watermelon and gourd, can be soaked with 10% trisodium phosphate for 20 minutes, washed with clean water and sowed.
