Agronomical indicators and incidence of insect borers of tomato fruits protected with non-woven fabric bags
ABSTRACT: Fruit bagging is an efficient mechanical control technique used in fruit growing. However, to date, few studies have evaluated the efficacy of bagging in the cultivation of vegetables, including tomato crops.

| description | ABSTRACT: Fruit bagging is an efficient mechanical control technique used in fruit growing. However, to date, few studies have evaluated the efficacy of bagging in the cultivation of vegetables, including tomato crops. The objective of this study was to evaluate the effectiveness of bagging of tomato flowers and/or fruits using a non-woven fabric (NWF) for the control of Helicoverpa spp., Neoleucinodes elegantalis, and Tuta absoluta, to evaluate the effect of this technique on the final yield, and determine the optimal period for bagging. Tests were conducted in a commercial crop of staked ‘Valerin’ tomato plants located in the municipality of Ubajara, Ceará State, Brazil. The experimental design was randomized blocks with a 2x4 factorial design (sprayed versus unsprayed plants, and both plant groups were bagged with NWF bags at different growth stages [flowers bagging, bagging of bunches of fruits with a diameter of 1.5cm, bagging of bunches of fruits with a diameter of 3.0cm, and unbagged bunches (control)], with five repetitions. We evaluated the number of fruits per bunch, number of bunches per plant, weight of each fruit, longitudinal and transverse diameter, percentage of bored fruits, yield loss caused by insect infestation, and final yield. Bagging of ‘Valerin’ tomato bunches with NWF bags was effective for the control of N. elegantalis, and productivity increased by 21.5% when bagging was done in bunches of fruits with a diameter of 1.5cm compared with unbagged fruits; therefore, this growth period was the most suitable for bagging. |
