Prevention and treatment of rose flower nodules
Symptoms: white nodules seen at the root. Young tumors are white and become hard later. The surface of the tumor is rough. Brown or dark brown, nodules grow to the ground when severe. The long nodule had bad rose growth, yellowed foliage, reduced root number, and multiple growth of nodule.
Incidence of the law: L nematodes in the spring and autumn in the two infection period within a year, the male, egg or second-instar larvae in the disease in winter, to survive in soil or tumors more than a year. After the nematode invades the rose root, it can stimulate the proliferation of the root bark cells of the rose, resulting in cancerous lesions.
Control methods: (1) Soak the roots of the plants with concentrated streptomycin 500-1000 times for 10 minutes before planting. (2) When grafting, the knife will be disinfected with high temperature or alcohol to prevent nematodes from immersing in the wound. (3) Coat the affected area with a mixture of methanol, glacial acetic acid, and iodine tablets (50:25:10); or use a mixture of sodium dinitropotassium powder and wood alcohol (20:80) to spread the affected area so that the tumor can disappear. .
