The incidence rate of tobacco climatic spots was reduced by 15%, and it was used correctly for two times in seedling stage

In recent years, the occurrence of tobacco climate related spot disease has been increasing nationwide. Tobacco climate spot disease is a physiological disease mainly caused by air ozone, nitrogen compounds, etc., and is one of the main tobacco diseases in the world. It belongs to non infectious diseases, indicating that it is not caused by viruses, bacteria, or fungi, and it is not contagious. But its ability to damage tobacco leaves is no worse than other diseases! Different degrees of climatic spots can affect tobacco grading, seriously affecting tobacco quality and the income of growers.

The incidence pattern of climatic spots is characterized by long-term low temperature and lack of sunlight. After transplanting, it is not possible to grow and develop quickly, resulting in uneven growth of tobacco seedlings, tender and weak tobacco plants, poor stress resistance, and susceptibility to diseases. In general, under conditions of low temperature, heavy rain, low sunlight, and sudden sunny weather with continuous cloudy and rainy weather, when the concentration of O3 in the air is high, it is easy to develop diseases and the harm is serious. After the thunderstorm, the illness was also severe. After watering, climate spots will occur, and the more frequent the watering, the more severe the climate spots will be. When the soil moisture is high, the application of phosphorus and potassium fertilizer is insufficient, and nitrogen fertilizer is excessive, the leaves will grow excessively and become thick, leading to severe disease. Tobacco fields with excessive planting density have a higher incidence of disease.

Summarizing the causes of climate related spots, climate is an external factor, while weak growth and nutrient imbalance of tobacco plants are internal factors. This year, the product application manager of Dingtian Jinong paid a return visit to several tobacco fields in Yingjiang, Yunnan, where Jinong Land was used, and found that the incidence rate of climatic spots was greatly reduced.

According to the statistics and data analysis, the incidence rate of climatic spots in tobacco leaves can be reduced by 15% after the application of two times of "Happy Land for Farmers" for planting and topdressing.

Jinong Letu regulates the soil, which has the functions of "nitrogen fixation", "phosphorus solubilization", and "potassium release", promoting balanced absorption of nutrients by the root system, more comprehensive absorption of water and fertilizer, and robust growth of tobacco plants, thereby increasing their resistance to stress and disease. At the same time, it has the function of water and fertilizer retention, which can maintain the soil moisture in the root system within the normal range for a long time, reduce the frequency of watering, and lower soil moisture. Take multiple measures to prevent the occurrence of climate related spot diseases.
