Title A name given to the resource PESTICIDAL PROPERTIES OF CHIVE (ALLIUM SCHOENOPRASUM)AGAINST CABBAGE APHID (BREVICORYNE BRASSICAE) IN RAPE (BRASSICA NAPUS) Creator An entity primarily responsible for making the resource SHADRECK KATURUZA, NYEMBEZI MGOCHEKI WISDOM KURANGWA Description An account of the resource The cabbage aphid is of agricultural concern vectoring at least 20 viral pathogens in crucifers. The aphids have demonstrated tolerance to a number of synthetic pesticides. Botanical pesticides are reasonably sustainable and effective in suppressing cabbage aphid populations in crucifers hence improved crop quality and yield per hectare. An experiment was run to test the efficacy of various concentrations of a botanical pesticide derived from chive (Alliumschoneoprasum in controlling cabbage aphid (Brevicoryne brassicae) in rape. The experiment was laid out in a Complete randomized design (CRD) with four treatments and four replicates as follows; 12g chive extract, 8g chive extract, 4g chive extract and 0g control (water spray). Analysis separate mean mortality was done using Gens tat version 18 and least significant difference at 0.05 probability level was used to separate means. SPSS version 20 was used in estimating LC excel was used in calculating the regression equation. Significant differences (p<0.05) were observed throughout the trial, where highest mortality rates were observed in 12g chive extract (94.5%) and lowest mortality in control (12.2%) was observed. Pesticide concentration atLC was estimated as a concentration of 7g/l. There were no observed signs of phytotoxicity even though other studies have shown that chances are high when the dose is increased. The experiments revealed that chive leaf extracts had pesticidal effects hence can be used to effectively control cabbage aphid in rape by smallholder vegetable producers.
