Agroecological Management in Vegetable Crops

Description

The increase in crops goes hand in hand with the increase in diseases and pests. Thus, phytosanitary problems are becoming a factor limiting production. Thanks to the application of synthetic pesticides, farmers have a very effective way to overcome these problems. However, the use of chemical products has more disadvantages than advantages for living beings and the environment. The search for alternative methods to the use of synthetic pesticides is now the subject of much work. An experiment was therefore conducted to propose an agroecological alternative to synthetic fungicides for the control of late blight of tomato in the field. The objective of this study was to evaluate the effect of the aqueous extract of Annona muricata seeds (AqEAM) against late blight and tomato yield parameters. Two varieties (Rio Grande and Lindo F1) constituted the main plots and three treatments (Aqueous extract of A. muricata, synthetic fungicide Mancozeb 800 g/kg and control) representing the subplots. Treatments were used in a split-plot design with four replicates. Treatments were applied two weeks after transplanting and the dose of AqEAM used was 70 g/L.
