Sometimes planting melons can cause gelation, so how can we avoid this phenomenon in production? Let us look at what measures should be taken and which pesticides should be used to treat this phenomenon. The main cause of melon stem and vine flow is the disease. At present, there are mainly anthracnose, bacterial fruit spot and blight.
Distinguish these diseases and popularize such a sentence in the Shouguang melon planting area: the anthrax flow red glue, the vine "V" word spotted brown glue, and the bacterial infection spots are irregular.
Secondly, physical and chemical control are combined to prevent disease and reduce medication.
Physical control:
First, we must choose resistant varieties. Such as cantaloupe, nettle, Shabai and other strong breeds, strong disease resistance.
Second, we must apply biological fertilizer. In particular, the sheds with long planting time can be used to apply biological fertilizers during the leisure period or at the time of planting, to inhibit bacteria and prevent infection and infection.
Chemical control:
One must disinfect the seeds and the shed. Soak seeds in warm water at 55 °C for 20 minutes, remove and dry, wash with water and soak for 48 hours with 47% spring and Wang copper WP 600 times. After rinsing, germination can prevent diseases caused by seed bacteria. The melon seedlings are sealed and disinfected before planting, and disinfected with potassium permanganate to prevent blight.
Second, rational use of drugs. Usually, farmers can choose bromoxynil or prochloraz to control anthracnose, copper copper, quinoline copper and other organic copper preparations to control melon fruit spot disease, generally choose 50% succinated acid copper 500 times mixed with 25% fresh The amine is 1500 times more resistant to these three diseases.
