Evaluación de microorganismos para el control de hernia de las crucíferas (Plasmodiophora brassicae) en el cultivo de brócoli Brassica olerácea Var. Avenger).

Abstract

In this study, the effectiveness of the application of microorganisms was evaluated using the Sauber product for the control of cruciferous hernia in broccoli cultivation (Brassica oleracea Var. Avenger), the study factors were dose and frequency of application. The experimental design used was the completely randomized block design (DBCA), with three treatments for three repetitions plus a control. The variables evaluated were plant height, seed weight, root volume, yield, and incidence. Analysis of variance (ADEVA) and Tukey's significance test at 5% were performed for each variable. The treatments were DI1F1, DI1F2, D1F3, D2F1, D2F2, D2F3, D3F1, D3F2, D3F3 and Control, D1, D2 and D3, doses of 2.5, 5 and 7.5 cc respectively and F1, F2 and F3, frequencies of eight, fifteen, and thirty days respectively. At the end of the analysis, 1t was determined that the best dose and frequency of application is the D3F] treatment, in which the dose of 7.5 cc/L was applied in drench with a frequency of every eight days, 1t 1s the best treatment due to Because in all the variables evaluated 1t presented better results compared to the other treatments in the study, this 1s because the greater the amount of microorganism, the better the control and having a good amount of organic matter in the soil helps the action of these microorganism 1s effective.
