Sweet pepper crops suffer major losses from anthracnose caused by Colletotrichum spp. In the present work we describe the combined effects of cultivation in the dry and rainy seasons, of nitrogen fertilization doses (0-450 Kg/ha), the use of organic (grass) and plastic soil mulches, as well as the application of a synthetic protectant fungicide (chlorothalonil) for disease control. Overall results indicate that choice of planting season is the most decisive factor for sweet pepper anthracnose management. Use of fungicide is a less decisive but still important factor, followed by choice of soil mulch substrate and nitrogen fertilization. The combined effects of all cultural practices were demonstrated: for instance, in the rainy season, fungicide alone was not as efficient as the combined use of fungicide and grass mulch. Conversely, in the dry season fungicide applications may be discarded, when organic soil mulch is adopted. The effects of the type of soil cover on the splash dispersal of Colletotrichum conidia are discussed. Management practices described here are of practical value for either organic or conventional growers.

通过选择种植季节、有机土壤覆盖物、杀菌剂和适度施氮来管理甜椒炭疽病

甜椒作物遭受炭疽病引起的炭疽病的重大损失。在目前的工作中，我们描述了旱季和雨季种植、施氮量（0-450 公斤/公顷）、使用有机（草）和塑料土壤覆盖物以及使用用于疾病控制的合成保护剂杀菌剂（百菌清）。总体结果表明，种植季节的选择是甜椒炭疽病防治的最决定性因素。杀菌剂的使用是一个不太重要但仍然重要的因素，其次是选择土壤覆盖基质和施氮肥。证明了所有文化实践的综合效果：例如，在雨季，单独使用杀菌剂不如杀菌剂和草覆盖物的组合使用那样有效。反过来，在旱季，当采用有机土壤覆盖物时，可以放弃使用杀菌剂。讨论了土壤覆盖类型对炭疽菌分生孢子飞溅扩散的影响。此处描述的管理实践对有机种植者或传统种植者都具有实用价值。
