There are significant differences in the efficacy persistence and residual characteristics of 98% prothioconazole in different agricultural ecosystems.
In greenhouse agricultural ecosystems, due to the relatively closed environment and adjustable temperature and humidity, the efficacy persistence of prothioconazole is relatively long. Stable environmental conditions are conducive to the formation of a protective film on the surface of crops, which can continuously exert a bactericidal effect, effectively prevent and control various diseases such as powdery mildew and rust, and reduce the number of drug applications. In terms of its residual characteristics, due to the limited space in the greenhouse, the volatilization and decomposition of the agent are relatively slow, and the residual amount may be relatively high, but if it is used strictly in accordance with the recommended dose and safe interval, it generally will not have a significant impact on the next crop.
In open field agricultural ecosystems, natural environmental factors such as wind, rain, and sunshine will affect the efficacy persistence of prothioconazole. Rainfall may wash away the agent on the surface of the crop, reduce its effective concentration, and thus shorten the duration of the efficacy. However, its good systemicity makes up for this deficiency to a certain extent, so that the pesticide can be absorbed by crops and conducted in the body, continuously resisting pathogens. In terms of residual characteristics, the open environment of the field is conducive to the volatilization and decomposition of the pesticide, and factors such as soil microorganisms will also accelerate its degradation, so the residue is usually relatively low, but it is also necessary to avoid excessive use near the harvest period to prevent excessive pesticide residues.
The orchard ecosystem has its own particularity, and the fruit trees have a long growth cycle and dense branches and leaves. Prothioconazole has a good prevention and control effect on various diseases of fruit trees in the orchard, and the drug effect is good. It can protect fruit trees from pathogens for a long time. In terms of residue, due to the perennial characteristics of fruit trees and the close distance between the edible part of the fruit and the application site, it is necessary to more strictly control the dosage and time of application to ensure that the pesticide residue in the fruit meets the safety standards and ensure the quality and safety of the fruit.
In conclusion, the persistence and residual characteristics of 98% prothioconazole technical in different agricultural ecosystems are different. In actual use, it is necessary to reasonably adjust the application plan according to the characteristics of the specific ecosystem to achieve the best control effect while ensuring the quality of agricultural products and ecological environment safety.
