Seize the time to control eggplant, melon and balsam pear diseases

Recently, when the technicians of Yong'an Plant Protection Station went to the countryside to investigate vegetable diseases and insect pests, they found that the muskmelon, balsam pear and eggplant transplanted by plastic film and arch shed cultivation at the end of February all had diseases to varying degrees. Eggplant diseases are mainly late blight, and the rate of diseased leaves is as high as 4.1%; muskmelon and balsam pear diseases are mainly blight or Fusarium wilt and blight. In the fields with heavy disease, the mortality rate of blight or Fusarium wilt was 5.8%, the mortality rate of balsam pear blight was 16.2%, and the rate of diseased leaves was as high as 9.2%. In order to prevent the spread and harm of the disease, it is suggested that the agricultural technicians in the township streets should go deep into the field investigation and actively guide the prevention and control of farmers. Suggested prevention and control measures are as follows: 1. Eggplant, muskmelon and balsam pear blight: when the weather clears up, immediately add foliar fertilizer with 800 times liquid of plague cream or 64% disinfectant alum 600 times liquid; unoccurred fields can be sprayed with 75% chlorothalonil wettable powder 600-800 times liquid plus foliar fertilizer, and it is best to spray twice, alternately, once every 7 days. 2. Muskmelon, balsam pear blight or Fusarium wilt: when the weather clears up, immediately use 50% carbendazim or dimethazone 600x solution to add 4500 times or 8000 times solution to irrigate the roots or 1200 times methyl phosphos EC plus 4500 times or 8000 times solution and other plant growth regulators to irrigate the roots, once every 5 days, twice in a row.
