As a highly effective fungicide, the conduction and distribution of 97% epoxiconazole in crop plants are of key significance for a deeper understanding of its mechanism of action and optimization of its use.
97% epoxiconazole enters crop plants mainly through root absorption and leaf spraying. When the roots come into contact with a solution containing 97% epoxiconazole, the agent will enter the root tissue through active absorption or passive diffusion of root cells. For example, after applying the drug to the roots of rice, 97% epoxiconazole can quickly penetrate the root epidermal cells and start its conduction journey in the plant.
After being absorbed from the roots, 97% epoxiconazole will be conducted upward through the xylem. The duct system of the xylem is like a highway. 97% epoxiconazole rises rapidly with the transpiration flow and can reach the aboveground tissues such as stems and leaves. In this process, its conduction speed will be affected by the physiological state of the plant, such as the intensity of transpiration. When transpiration is vigorous, the conduction speed is accelerated, and the agent can be distributed more quickly to all parts of the plant.
When spraying on leaves, 97% epoxiconazole will first spread on the leaf surface and penetrate into the mesophyll cells. Part of the agent will exert a local bactericidal effect in the mesophyll cells, while the other part will be transversely and longitudinally conducted through the vascular system of the leaves. Transverse conduction can diffuse the agent in different parts of the same leaf, while longitudinal conduction can transport the agent to the petiole, stem and other parts.
In the plant body, the distribution of 97% epoxiconazole is not uniform. Usually, the concentration of the agent is relatively high in new tissues and parts with vigorous growth, such as young leaves and tender shoots. This is because the cells in these parts have active metabolism and strong absorption and accumulation capabilities of the agent. In old leaves and mature tissues, the concentration is relatively low, but it can still maintain a certain antibacterial concentration to prevent disease infection.
There are differences in the conduction and distribution characteristics of 97% epoxiconazole in different crop types. For example, in wheat plants, 97% epoxiconazole conducts faster and can maintain a higher concentration in the ear for a longer period of time, effectively protecting the wheat ear from disease attack; in fruit trees, due to their complex tissue structure, the conduction of 97% epoxiconazole may be relatively limited, and a more precise application method is required to ensure that the agent can reach key parts.
Environmental factors can also affect the conduction and distribution of 97% epoxiconazole in plants. When conditions such as temperature, humidity, and light change, the physiological activities of crops change accordingly, which in turn affects the absorption, conduction speed, and distribution range of the agent. For example, in a high temperature and high humidity environment, crop growth is accelerated, which may accelerate the conduction of 97% epoxiconazole, but it may also cause the agent to be lost too quickly due to excessive transpiration.
In-depth research on the conduction and distribution of 97% epoxiconazole in crop plants will help to scientifically formulate application plans. The dosage, time and method of application should be reasonably determined according to different crops, different growth stages and environmental conditions, so as to maximize the bactericidal effect of 97% epoxiconazole, reduce the use of pesticides, ensure the quality and safety of agricultural products and the sustainability of the agricultural ecological environment.
