How can field management be done well during corn cultivation?
How should corn be managed when planting? Please give suggestions. With excessive rain, corn diseases and weed problems will be more severe than in previous years. Therefore, the following suggestions are offered for this year's corn planting and management. 1. Strengthen seedling-stage disease control. Because of frequent rain, high soil moisture, and lower-than-usual soil temperature, corn emergence will be relatively delayed, increasing the possibility of seed rot and seedling death. The focus of control is seed coating. You can choose Shileshi 2.5% water suspension concentrate. Usage: one bag of Shileshi (10 ml), add 100 ml to 150 ml of water, pour into an enamel basin or plastic bag, then add 3 kg to 5 kg of corn seed, stir forcefully or shake evenly so that the liquid medicine evenly coats the seed surface. The coated seed can be sown promptly without drying. You can also add 10 ml of phoxim or isofenphos-methyl to the liquid to also control underground pests.
