粉锈宁是当前防治小麦锈病的最有效药剂,但其售价较高,药源不足,不宜于长期单一使用。为此,寻找药源充足,价格低廉的保护性药剂,与之混用,是解决这些问题的主要途径之一。硫磺制剂系资源丰富、成本低廉、杀菌广谱、但药效不高、持效期短的保护性药剂,因而与之混用比较合适。粉硫混剂是粉锈宁与硫磺混配的剂型,经温室和田间大、小区试验结果表明,防治锈病效果显著,是值得推广应用的好剂型。

Triadimefon is currently the most effective anti-wheat rust agent, but its higher price, lack of source, not suitable for long-term single use. To this end, looking for adequate source, low price of protective agents, mixed with them, is one of the main ways to solve these problems. Sulfur preparation is rich in resources, low cost, bactericidal broad-spectrum, but the efficacy is not high, short duration of the protective agents, so with the more appropriate mix. Powder sulfur mixture is a mixture of triadimefon and sulfur formulations, the greenhouse and the field large, cell test results show that the effect of preventing rust is significant, it is worth promoting the use of good dosage form.
