The specific prevention and control methods are as follows: first, the mixture of 1500 times plant virus vaccine, 1500 times natural brassin and 4000 times golden crown (30% difenoconazole propiconazole) should be sprayed on the leaf surface every 10 to 15 days. Spray all leaves evenly, so that it is appropriate to start dripping water. Secondly, the roots should be sprayed with a mixture of 300x zinc sulfate, 1500 times endosulfan, 300x magnesium sulfate and 300x potassium nitrate every 10 days, each time 2kg per hole. In this way, the virus activity in black-skinned sugarcane seedlings can be inhibited and weakened, the virus can be killed, the aphids and thrips that spread viral diseases can be eliminated, the disease of black-skinned sugarcane seedlings can be controlled, and the diseased plants can return to normal growth. the yellowed leaves turn to dark green, the stems and leaves are thick, the roots are developed, the plants are vigorous, and the plants enter the jointing and elongating stage smoothly.
