Agroecological management of anthracnose (Colletotrichum gloeosporioides) in the flowering and fruiting stages of mango (Mangifera indica)
Main Article Content
Abstract
Anthracnose is the main disease affecting the mango crop, especially during the flowering and fruit set stages. The objective of the research is to evaluate the efficacy of three agroecological products of mineral and biological origin copper sulfate pentahydrate, sulfocalcic broth and Bacillus subtilis for the control of the fungus Colletotrichum gloeosporioides in the flowering and fruiting stages of the Tommy Atkins variety of mango. A randomized complete block design (RCBD) was used, with 5 treatments and 4 replicates. The treatments with the highest degree of affectation were the absolute control T5 and Bacillus subtilis T2 with a percentage higher than 70% for the variables described; on the other hand, the treatments with the least affectation were copper sulfate pentahydrate T1, sulfocalcic broth T3 and the conventional control T4. The treatments copper sulfate pentahydrate T1 and sulfocalcic broth T3 obtained a similar result of efficacy in the control of anthracnose to that obtained with the conventional control T4 of synthetic origin. Of the three agroecological products evaluated, copper sulfate pentahydrate and sulfocalcic broth achieved a better efficacy result than Bacillus subtilis. Therefore, the application of copper sulfate pentahydrate and sulfocalcic broth is recommended as a viable alternative for the control of anthracnose in Tommy Atkins mango.
