Abstract
This study of effectivelypreventing harmful insects on cherry tomato plants with vegetation extractsfrom chilli, garlic, chilli-garlic, and Neem tree (Melia azedarach) extract were conducted at the Experimental Area, An Giang University. The experiment with 5 treatments (each of 3 plants) and 3 replications was carried out in the period from January 1st, 2018 to April 20th, 2018. The results showed that all four extracts were highly effective, andthe Neem extractwas the bestat 3 and 5 days after spraying over 50%. Specifically, for aphids (Aphis gossypii)it reached 78.71% after 7 days of spraying; forleafworm moth (Spodoptera litura) 66.72% after 3 days of spraying; and forsilverleaf whitefly (Bemisia tabaci) 77.46% after 1 day spraying. The Neem extract is considered the most effective herbalsincontrolling cherrytomato insects.
