苹果霉心病防治的研究

A STUDY ON THE CONTROL OF APPLE MOULD CORE

试验结果表明:①在我们使用的药剂中,波尔多液防治苹果霉心病效果最好;②施药期是防治苹果霉心病的关键,施药期不适当,同一种药剂的效果表现不同,如多菌灵·从暴芽或蕾期开始防治效果最好;③B_(25)和A_(32)在田间防治苹果霉心病有一定效果,因此生防问题值得进一步研究。

Experiments showed as the following: Ⅰ.In fungicides used by us, Bordeaux mixture was the best to contol the mould core of apples. Ⅱ.The date of the beginning to spray the fungicides was the most important key. The various initial date would lead a different result even if the same fungicide was used, such as carbendazol, spraying fungicides from budburst or flower budding period to control the desease was the best. Ⅲ.B25 and A32 selected by us were the better to control the apple mold core in the fields. Biological control was worth to continue to test.
