How to apply herbicides to watermelons? What do you need to pay attention to? In order to reduce and prevent mistakes in the application of chemical herbicides to watermelons, attention should be paid to the following problems in application techniques. First, choose herbicides correctly. There are many kinds of herbicides available in watermelon production. The most commonly used are 48% trifluralin EC, 25% herbicide wettable powder, 33% herbicide EC, 48% Deletamine EC, 12.5% herbicide EC, 15% trimethoprim EC, 15% trimethoprim EC, 48% Lasol EC, 10% herbicide EC and so on. Second, strictly grasp the dosage. 48% trifluralin 75-125 ml per mu, 25% herbicide 100-150 g per mu, 33% herbicide 80-130 ml per mu, 48% trimethoprim 200 ml per mu, 12.5% cover grass can 65-150 ml per mu, 15% steadily kill 75-130 ml per mu, 15% firmly kill 50-60 ml per mu, 48% lasso 150-200 ml per mu, 10% herbicide 65-100 ml per mu. 40-50 kg of water was mixed respectively and sprayed on the surface of the soil before watermelon transplanting. Among them, fluralin is easy to decompose after seeing the sun, and the medicine soil will be raked evenly with tooth rake after spraying, with a depth of up to 5 cm, so that the efficacy can be brought into full play. Third, it should be applied flexibly according to the place and time. The effect of herbicide application on watermelon is closely related to the ecological environment, for example, the effect of herbicide application in sandy loam is faster than that in clay, but it is safer in clayey soil, and the higher concentration of sandy loam is easy to cause drug damage. It is necessary to accurately control the dosage according to the soil. The effect of killing weeds is better when the temperature is above 20 ℃. When the temperature is not high in spring and autumn, the dosage should be increased appropriately, and the dosage should be reduced when the temperature is high in summer. The weeding efficiency is high when the soil moisture is good, and the weeding effect decreases when the soil moisture is poor, so the medicine should be used when the soil moisture is good.
