To guard against the spread of wheat stripe rust, experts say that the weather should warm up in February
Due to the advanced sowing date and high temperatures, wheat fields in strips rust occurred five months earlier in the wheat fields of Nanyang, Sheqi and Zhoukou in our province. Provincial Academy of Agricultural Sciences experts reminded that the current low temperature spores spores are temporarily suppressed until the warmer weather in February, strip rust may spread across the province, all localities must pay close attention to prevention, so as not to cause wheat production. According to Wei Deyong, senior agronomist and director of the Agricultural Technology Promotion Center of Sheqi County, due to the proper application of prevention and control technologies such as seed treatment before wheat seeding, other wheat pests and diseases in Sheqi County have a small scope and a low degree, while wheat stripe rust has a severe incidence. In October last year, Sheqie County discovered wheat strip rust, and spread quickly afterwards. The time is early and the area is large, and the history is rare. It is understood that the severer wheat stripe rust has occurred earlier in the provinces such as Nanyang and Zhoukou. According to Wang Shaozhong, a researcher at the Wheat Research Institute of the Provincial Academy of Agricultural Sciences, wheat stripe rust is the first disease type of wheat disease and usually occurs in April, due to the early sowing of winter wheat in various places, and the high temperatures in September and October last year. The high humidity in the air provided favorable conditions for the infection of the stripe rust pathogen, leading to the early occurrence of wheat stripe rust. After the occurrence of stripe rust, there will be strips of rust on the leaves of wheat, the leaves can not carry out photosynthesis, resulting in withering, necrosis, resulting in a serious decline in wheat production. Stripe rust occurred in a large area of ​​our province in November last year. Due to the cold weather, spores of stripe rust have been temporarily suppressed. If the temperature rises, these latent pathogenic bacteria will cause the disease to spread. Wang Shaozhong reminded the majority of farmers that they should not be taken care of. If the weather turns warmer in February, prevention and control should be carried out immediately to prevent widespread spread. The prevention and control of wheat stripe rust should adhere to the principle of “discovering one point and controlling one†to minimize the sources of overwintering bacteria, reduce the number of pathogenic bacteria in the middle and later stages, and reduce the field disease index. Wei Deyong recommends the following methods of prevention and treatment: 15% triadimefon wettable powder can be used, and 75 to 100 grams of water and 40 kilograms of water can be sprayed for mu. Or mu with 12.5% ​​of particles wettable powder 20 ~ 25 grams of water 35 ~ 40 kg of spray, or 25% of the mu with 20 ~ 30 ml of water 30 ~ 40 kg spray. Since the pathogen of wheat stripe rust is mainly on the back of wheat leaves, the back of the leaves should be used mainly when spraying. In order to improve the adhesion of liquid medicine on the leaf surface, a small amount of washing powder and liquid medicine should be added after the liquid is mixed thoroughly to spray.
