- Abstract
An experiment was carried out at Horticultural Research Centre Marondera, Zimbabwe during 2011-12 to determine the effect of Allium sativum as a repellent crop to control diamondback moth (DBM) in cabbage. The trial was laid out in RCBD with four treatments. Garlic was intercropped with cabbages in 2:1 and 2:2 ratios. Diamondback moth larval counts were affected by treatments (P = 0.05). Hence sole cabbages unsprayed with malathion 25WP showed significantly higher counts than the other treatments from week 3 to 8 after transplanting. There were no significant differences (P = 0.05) in larval populations between intercropped plots and chemically-treated plots. Cabbage quality was poorest in sole cabbages that were not sprayed with malathion 25WP, with a score of 2.85. There were no significant differences between garlic intercropped cabbages (2:2) and those treated with malathion 25WP. Cabbage yield in garlic + cabbage intercropped plots (1:2) was similar to that achieved in plots treated malathion 25WP. The results showed that garlic intercropping can be used to manage DBM effectively. Use of garlic is environment friendly, and farmers can also derive additional benefits from garlic.
