The efficacy assessment of emamectin benzoate using micro injection system to control red palm weevil

Red palm weevil is the most injurious pest on dates globally. The purpose of this field trial was to evaluate the preventative & curative effect of the micro emulsifier insecticide Emamectin Benzoate in two formulations: Revive® 4 % and ReviveII® 9.5 % against the red palm weevil for one year. A completely randomized block design was applied on 36 mid to high infested trees with 4%,9.5% and the control. One single direct micro-injection was applied at the base of the trunk using Syngenta TMI 4.1 device, under low pressure of 2 bar. Biweekly monitoring for Red palm weevil external symptoms of treated trees. Treated Trees were cut and dissected after: 3, 6, & 12 months from injection date collecting all RPW individuals from the out side and the inside of the tree trunk, it was found that RPW mean mortality% cause by Revive was 88.1 and 98.8for ReviveII®9.5%. descriptive symptom data and RPW mortality% inside the trunks showed that trees injected by Revive®4% and ReviveII®9.5% were cured 100% from RPW for one year by killing renewable infestation. LOQ of Emamectin benzoate were quantified in fruit and compared with MRL level after 60 and 100 days. Results indicated that no residues of ReviveII® in fruit samples after 60days.
