This year, the incidence of black-skin cane mosaic virus disease is early, and the potential is fierce. The damage is serious. At present, many black-skin cane seedlings show yellowing and yellowing of the leaves. The new roots are atrophic, gradually die, and do not grow new leaves. Slowly, if it is not controlled in time, it will spread rapidly, increase the damage, make the stem section thin and long, and the cane skin becomes flower, eventually forming a "flower-skin cane", losing the value of food and commodity value. Therefore, at present, we must pay close attention to the prevention of mosaic virus disease to protect the seedlings of black-skin cane.
Specific prevention methods are as follows: First, spray 2-3 times 1500 times plant virus vaccine, 1500 times natural brassin, and 4000 times gold crown (30% difenoconazole) in a foliar spray. Spray once every 10 to 15 days and evenly spray all the leaves to start dropping drops of water. Secondly, apply 2-3 times of zinc sulfate, 1500 times 35% endosulfan, 300 times magnesium sulfate, and 300 times potassium nitrate mixture to the roots every 2 to 3 times. Apply once every 10 to 15 days. ~3 kg. In this way, it is possible to suppress and weaken the virus activity in the seedlings of the black-skin cane plants, kill the viruses, eliminate the aphids and thrips that transmit virus diseases, control the incidence of black-skin fruit cane seedlings, and accelerate the normal growth of diseased plants. The leaves of yellowing turn into thick green, the stems are thick and the leaves are thick, the root system is developed, the growth is vigorous, the plants are robust, and they smoothly enter the elongation stage of jointing.
