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).
