Top seedling new seed dressing to control rice seedling disease

Top seedling new 4.23% nail cream · inobutazole microemulsion containing metalaxyl 1.88%, inoculum 2.35%, registered for the control of rice seedling disease and blight, corn stem rot and head smut, Cotton blight. According to the technical staff of Alice Star Bio-Chemicals North America Co., Ltd., there are five major phytopathogenic fungi in nature. The inoculum can prevent and control four of them, while metalaxyl is only effective against oomycetes. The combination of inobutazole and metalaxyl is perfect, and the two active ingredients have complementary advantages, which can effectively prevent and cure a variety of species and soil-borne diseases. The medicine not only can disinfect the outside of the seed, but also can prevent the hyphae that have been infected into the inside of the seed, and can be transmitted to the seedlings and other parts to prevent further infection of the bacteria.

Rice seedling disease has not been serious in Jiangsu Province in the past, but it has been widespread in southern Jiangsu, along the Yangtze River and coastal areas in recent years. The disease is a disease mainly caused by seed transmission, and the traditional soaking and germination sowing method opens a convenient door for the infection of the seedling pathogen. The seed-bearing seeds contaminate healthy rice during the soaking process, and the number of infected rice species is increased. After the rice seeds are germinated, the pathogens invade from the buds cause the seedlings to develop, and the diseased plants show long symptoms.

After rice seedling disease occurs, there is no medicine to cure, and treatment of rice seeds is the most effective measure to prevent and cure disease. At present, the drugs such as prochloraz and cymene which are registered for the prevention and control of rice seedling disease need to be immersed in the method of immersion, which is troublesome in operation and inoculation, and the risk of vaccination is increased. Top seedlings only need seed dressing to effectively control rice seedling diseases and other soil-borne diseases, and it is easy to operate and saves labor. According to the results of the pot experiment on the prevention and control of rice seedlings by the fungicide project team of the Plant Protection College of Nanjing Agricultural University, the fresh seedlings with top seedlings have better control effect against the disease. The drug is 133 ml, 200 ml, 300 ml. The treatment effects of mixing 100 kg of seeds were 91.43%, 92.86%, and 98.57%, respectively, which were significantly higher than those treated with 25% prochloraz emulsifiable concentrate 3,000 times (control effect 77.14%). Use this medicine to control rice seedling disease, generally use 1 ml of new seedlings and 10 ml of water to mix 0.6-0.75 kg of rice.

The new seedlings have high safety. Among them, the inoculum is different from the commonly used azole fungicides. It is very safe for rice and will not affect the emergence of rice. According to the test, rice seeds were mixed with the drug three times, and rice emergence was not affected. The germination rate of the rice seeds after seed dressing treatment was not significantly affected even after being left for a while.

The unique dosage form is also a new highlight of the top seedling. Compared with the shortcomings of suspending agent, it is not easy to dissolve. Microemulsion has the advantages of good solubility, no sticky bag and easy cleaning. The demonstration of the dosage form on site proves the superiority of microemulsion.

In addition to the characteristics of good disease prevention, high safety and unique dosage form, Top Seedling has the function of promoting roots and strong seedlings.
