PEMANFAATAN EKSTRAK BIJI MAHONI SEBAGAI PESTISIDA NABATI UNTUK MENGENDALIKAN HAMA ULAT GRAYAK (Spodoptera litura F) PADA PEMBIBITAN Acacia crassicarpa A. Cunn. ex Benth.
Abstract: Acacia crassicarpa
is one kind of plant that was developed as industrial timber plantations. This
plant has a rapid growth rate are very adaptable and tolerant of environmental
conditions are extreme. Acacia crassicarpa nursery is a stretch of similar plants
are very susceptible to the pests. One of the pests that often attack the young
plants in the nursery is Spodoptera litura F. The efforts to control this pest
is generally controlled by using chemical pesticides. The use of mahogany seed
extract as a botanical pesticide for controlling Spodoptera litura F. of the
Acacia crassicarpa nursery is an alternative that can be used as an
environmentally friendly pesticide. This research aimed to know the potential
of mahogany seed extract in controlling Spodoptera litura F. and determine the
exact concentration of the level of Spodoptera litura F. mortality of the
Acacia crassicarpa nursery. This research uses a Completely Randomized Design
Method, which consists of 4 treatments and 4 replicates with concentration
levels of botanical pesticide. T0 = concentration mahogany seed extract 0 g/l
of water; T1 = 10 g/l of water; T2 = 20 g/l of water; T3 = 30 g/l of water. The
results showed that the application of mahogany seed extract at the
concentration of 30 g/l of water is the best concentration in controlling
Spodoptera litura F. with results initial time of death fastest is 2.75 hours
(2 hours 45 minutes), the fastest time of turning off 50% (LT50) is 18.00 hours
and total mortality amounted to 72.50%.
