Abstract:
Red pepper (Capsicum annum L.) constitute one of the important vegetable commercially to cultivated in the tropics and have high economic value. Cultivation of chilli in riau have continued increases very fast, but in production of chilli very decrease. One of causes production of chilli decrease is incursion from peach aphids (Myzus persicae) pest. which damage the plant by sucking the liquid in the plant tissue. Effort control this pest still to use synthetic chemical insecticides, but synthetic insecticides can cause negative effects such as pest resistance and pest resurgence. To remember impacts negative of use synthetic insecticides, so I have sought other method solution to control peach aphids pest with safe and effective. With application vegetable insecticides using the fruit betel forest (Piper aduncum L.). The fruit betel forest can to control peach aphids (Myzus persicae) on the chili of plant. This research was conducted at the Pest of Plant Laboratory Faculty Agriculture Riau University Campus Bina Widya in Pekanbaru that lasted for 3 month (February to may). The research was conducted using design random of completely (RAL) method with 5 handling and 5 repetition there SRH0 (without extract flour the fruit betel forest) SRH1 (with extract flour the fruit betel forest 25g/L of water) SRH2 (with extract flour the fruit betel forest 50g/L of water) SRH3 (extract flour the fruit betel forest 75g/L of water) SRH4 (with extract flour the fruit betel forest 100g/L of water). Concentration extract flour the fruit betel forest 75g/L of water is an appropriate concentration in controlling the aphid Myzus persicae pest with the percentage of total mortality by 90% and value LC95 amounted to 7.15%.
