UJI BEBERAPA KONSENTRASI Beauveria bassiana Vuillemin LOKAL DALAM MENGENDALIKAN HAMA KEPIK HIJAU (Nezara viridula L.) (Hemiptera: Pentatomidae) PADA TANAMAN KEDELAI (Glycine max L.)
ABSTRACT: Nezara viridula is a
pest that can reduce soybean production both in quality and quantity. Currently
efforts in controlling N. viridula still use synthetic chemical insecticides
that can have negative impacts. One solution to reduce reliance on synthetic
chemical insecticide is the use of entomopathogenic fungi Beauveria bassiana.
The purpose of this study was to test the ability of several concentrations of
entomopathogenic fungi Beauveria bassiana Vuillemin Riau local green ladybugs
for pest control N. viridula on soybean plants. Research prepared using completely
randomized design (CRD) with 6 treatments and 4 replications. The treatment
used is some concentration of B. bassiana consists of 6 treatments are: 0 g/ l
of water, the concentration of B. bassiana 70 g / l of aquades, the
concentration of B. bassiana 75 g / l of aquades, the concentration of B.
bassiana 80 g / l of aquades , the concentration of B. bassiana 85 g / l of aquades,
the concentration of B. bassiana 90 g / l of aquades. The results showed
concentrations of B. bassiana 90 g / l of aquades is more effective in
controlling N. viridula, but to fulfill the concept of integrated pest control
concentration of 80 g / l of aquades (17.42 x 107 kon / ml) are considered
better because it can lead to early N. viridula death for 64.25 hours, lethal
time 50 (LT50) for 135.75 hours, and caused total mortality 85% for 9 days (209
hours).
