Abstract

Vitex pubescens Yahl is a native hardwood tree to Malaysia. Vitex pubescens Yahl is considered an invasive tree in agricultural land of UPMKB especially in the local fruits garden. The invasion of V. pubescens Yahl disturbs the development of fruits tree and restricts the management practices in the fruits garden. This study decides to test the effective technique to control V. pubescens Yahl. There are three techniques involved namely debarking, hack and squirt (triclopyr), and stem injection (triclopyr) were used to evaluate the percentage of foliage loss and stem mortality in the period of five months. This study was conducted in Randomize Complete Block Design (RCBD) where the tree size categorized based on stem diameter (small, medium and large). Collected data was further analysed by using ANOVA and Tukey mean comparison at a= 0.05. Hack and squirt method is the most appropriate techniques to control V. Pubescens Yahl by achieving high rate of foliage loss and trunk mortality with small-sized tree sample recorded up to 100% loss of leaves, medium-sized tree sample reached 92.5% loss of leaves, and large-sized tree sample achieved 81 % loss of leaves. Hack and squirt techniques found to be very effective compared to debarking and injection of stem because of high rate intake of poison penetrated into the bark cells and sapwood of trees. The correct technique helps in controlling the invasive V. pubescens Vahl in the local fruits of UPMKB and will help the farm management in the future.
