摘要:

为探索芒果花果期喷施杀菌剂而实现防控采后炭疽病的方法,选取露娜森和拿敌稳杀菌剂开展采后炭疽病防治试验。设计每种杀菌剂2个施药剂量梯度,咪鲜胺试验区,另设空白试验,共6个处理,比较各药剂处理间病情指数。试验结果表明,本实验所选用的药剂对芒果花果期的嫩叶、花、幼果未见药害,也不影响芒果的后熟,且采后7天时,花果期喷施1500倍浓度的露娜森的防效与采后浸果咪鲜胺的防效相当、防效达72.73%,货架期可维持7天,750倍浓度拿敌稳次之,对芒果炭疽病的采后储藏期有较好的防治效果,明显延长了芒果的货架期、储藏期。由于露娜森中含有新型的琥珀酸脱氢酶抑制剂——氟吡菌酰胺的原因,其作用机理是抑制了琥珀酸脱氢酶的活性。琥珀酸脱氢酶抑制剂类杀菌剂通过干扰复合体Ⅱ上4个亚基来抑制线粒体的功能,阻止其产生能量,抑制病原菌生长,与咪鲜胺处理的结果一致,具有一定的推广应用价值。

Abstract:

In order to explore the methods of controlling postharvest anthracnose by using fungicide in mango flowering and fruiting stage, Luna Sensation and Nativo fungicides were selected to carry out the experiment of postharvest anthracnose control. A total of 6 treatments were designed, including two application dose gradients of each fungicide, a prochloraz test area and a blank test, to compare the disease index among the treatments. The results showed that the fungicides used in this experiment did not harm the young leaves, flowers and young fruits of mango at flowering and fruiting stage, nor did they affect the ripening of mango. 7 days after harvest, the control effect of Luna Sensation sprayed with 1500 times of concentration was equivalent to that of prochloraz, and the control efficiency reached 72.73%, the shelf life could be maintained for 7 days. The control effect of Nativo sprayed with 750 times of concentration was the second, its control of mango anthracnose during the postharvest storage period was effective, and the shelf life and storage period of mango were prolonged obviously. The presence of a new succinate dehydrogenase inhibitor in Luna Sensation, named fluopyram, could work by inhibiting the activity of succinate dehydrogenase. Succinate dehydrogenase inhibitors impede the mitochondrial function by interfering with four subunits of complex II, inhibiting the production of energy and the growth of pathogenic bacteria. The fungicides in this study are consistent with prochloraz in treatment and have a certain value of popularization and application.
