The underground pests that occur in the fields often bite the seeds or bite off the underground rhizomes to cause the seedlings to die; or to feed on the underground rhizomes to make the crop grow weaker and affect the yield and quality of the melons. How to solve this problem? Over the years, there have been two misunderstandings regarding the control of underground pests. The first is the abuse of pesticides. In order to control pests, melon farmers are not afraid to use highly toxic and highly toxic pesticides such as carbofuran. Second, misuse of pesticides, and some melon farmers do not understand the knowledge of pesticides, the use of melon-sensitive phoxim ion, resulting in the death of melons. Try the following methods. (1) Apply adequately cooked organic fertilizer and mix a certain amount of medicine in the manure. The dosage is 1000 times for diazinon 50g or 80% dichlorvos EC. (2) Fall over the ground to kill some of the winter crickets. (3) Select coated seeds. (4) After discovering the hazards of underground pests, it is necessary to promptly use drugs to irrigate the roots. The pharmaceutical agent is selected to be Le Siben, and the amount of mu is 400-500 ml. (5) The application amount of soil worms is 4000-8000 grams. The control effect is also good.
