THE STUDY AND USE OF BOTANICAL PESTICIDE “CHILLI + GARLIC + GINGER” ON PRODUCTION OF VEGETABLES (BRASSICA OLERACEA) 2016-2017 IN HA GIANG

Abstract

The growth time of cabbages in treatment CT₄ (sprayed by the botanical pesticide “Chilli + Garlic + Ginger”) (b) was shorter than the control 1 (control 1: used water) (a) and longer than the control 2 (control 2: sprayed by the chemical pesticide Nurelle D 2.5EC) (c). But the growth time of cabbages in treatment CT₄ (sprayed by the botanical pesticide “Chilli + Garlic + Ginger”) (b) and in the control 3 (control 3: sprayed by the botanical pesticide Sokupie 0.36AS) (b) not signifacant diference in Duncan’s multiple range test.

The use of the botanical pesticide “Chilli + Garlic + Ginger” showed to effectively and fast control the insects (the outcome was  20.94 – 30.91% after 1 day spray and 75.03 – 77.97% after 5 days spray).

The yield of cabbage in CT₄ (sprayed by the botanical pesticide “Chilli + Garlic + Ginger”) (12.91a – 13.27a tons/ha) was not signifacant diference in control 3 (control 3: sprayed by the botanical pesticide Sokupie 0,36AS) (12.86a – 13.08a tons/ha) in Duncan’s multiple range test.

The yield of cabbage in CT₄ (sprayed by the botanical pesticide “Chilli + Garlic + Ginger”) (12.91a – 13.27a tons/ha) was higher than the control 1 (control 1: used water) (9.73c – 10.17c tons/ha) and the control 2 (control 2: sprayed by the chemical pesticide Nurelle D 2.5EC) (11.28b – 12.96b tons/ha).
