Dose Test and Application Ways Biofungiside Bacillus sp. Against White Root Fungi(Rigidoporus lignosus) on Rubber of Plants in the Nursery. This study aims to determine the effectof dose and ways application biofungiside with of Bacillus sp. against white root fungi(Rigidoporus lignosus) on rubber of plants in the nursery, as well as determine the effect of thewhite root fungi disease on the bud tall of rubber stump. The research was conducted usingRandomized Block Design (RAK) factorial consisting of two factors and 4 replications. The firstfactor, namely P0: control, P1: 20ml/1 liter water, P2: 30ml/1 liter water, P3: 40ml/1 liter water andthe second factor A1 (spraying) and A2 (deeping). The result showed the dose treatment containedthe highest intencity of the attacks on the P0 of 88,54% and lowest in P3 at 20,83%. Waysapplication treatment intensity of the attacks on the A1 of 35,94% and A2 at 54,69%. Interactionsof dose and ways application of the highest intensity of attacks are on P0A2 of 89,59% and lowestin P3A1 at 6,25%. The highest bud tall on dose treatments contained in P3 of 17,78 cm, the lowestin the P0 of 3,52 cm. Ways application treatment in A1 of 14,78 cm and A2 of 9,87 cm.Interactions in the bud tall of dose and ways application was highest in P3A1 of 21,04 cm, thelowest in P0A2 of 3,00 cm.

Epizootic study of Metarhizium anisopliae against Larvae Tritip in greenhouse. The objective of this experiment to know the effectiveness of the mechanism of transmission of the fungi M. anisopliae by larvae tritip in greenhouse. The research was conducted in Greenhouse Crops Research Institute for Tropical Fruit Tongkoh-Berastagi. The research used non-factorial completely randomized design with 5 treatments and 4 replications, which were: control(without infected by M. anisopliae), 5 larvae are infected by (5g, 10g,15g, 20g)/100ml M. anisopliae are transmitted to 5 healthy larvae. The results showed that the concentration addition of each suspension fungi M. anisopliae increased the mortality of larvae infected directly by immersion, mortality is transmitted. The concentration addition of the suspension fungi M. anisopliae increased transmission between larvae infected directly immersion method to healthy larvae and can also reduce the intensity of the attacks tritip larvae. The highest percentage of larvae mortality infected directly immersion method was 52,5%. The highest percentage of transmitted larvae mortality was 32,5% . The highest percentage of entirely larvae mortality was 95% . The highest percentage of larvae was growed by fungi was 92,5%. The highest percentage of damage was 59.25%. Key words : Epizootic, biological control, Plutella xylostella L, Metarhizium anisopliae.

The research was held at the Greenhouse OfAgriculture Faculty University of North Sumatera, Medan since June – August 2013. The methodof this research was Completely Randomized Design Non Factorial with 8 treatments and 3replications. Treatments being tested is K0 (control), A1, A2, A3 (25, 50, 75 ml tuba rootextracts/litre of water), T1, T2, T3 (25, 50, 75 ml tobacco extracts/litre of water), and AT (50 mltuba root extracts/litre of water + 50 tobacco extracts/litre of water). The parameters includethe percentage of mortality pest and the death of imago. The result showed that the most effective ofbotanical insecticides was found in treatment AT (100%) at 3 days after application, followed by T3(100%) at 4 days after application and T2 (96,67%) and A3 (95%) at 5 days after application, andless effective was found in A1 (81,67%) and T1 (88,33%) at 5 days after application, and on the 6days after application all botanical insecticides treatmens has show 100% mortality. The death ofimago is the fastest in treatments AT, T3, T2, A3, A2 and T1 occurred at 1 day after planting, andlongest are on treatments A1 occurred at 2 day after planting.Keyword: botanical insectisides, L. acuta, mortality, the time death
