Abstract

This research aims to obtain a concentration of soursop leaf flour extract which is effective to control the larvae of Oryctes rhinoceros L. The research was conducted at the Plant Pest Laboratory, Faculty of Agriculture, Riau University. The research was conducted for two months from April 2019 to May 2019. The research was conducted experimentally using a completely randomized design (CRD) consisting of 5 treatments and 4 replications, so that 20 experimental units were obtained. The treatments given were the concentration of soursop leaf extract 0 g.l-1 water, 25 gl-1 water, 50 gl-1 water, 75 gl-1 water and 100 gl-1 water. The parameters observed were the initial time of death, lethal time, lethal concentration, daily mortality, total mortality, temperature and humidity. The observed parameters data were analyzed by variance and followed by LSD at 5% level. The results showed that giving of soursop leaf powder extract at the higest concentration is 100 g.l-1 water was control O. rhinoceros L. larvae with a total mortality of 60%. This has not been effective in controlling O. rhinoceros L. larvae because it has not been able to cause a total mortality above 80%. The correct concentration caused a total mortality of 50% of O. rhinoceros L. larvae was 8.4% or the equivalent of 84 g.l-1 water extract of soursop leaf flour. The concentration that was able to produce a total mortality of 95% of O. rhinoceros L. larvae was 55.2% or the equivalent of 552 g.l-1 water extract of soursop leaf flour. Keywords:Oryctes rhinoceros, extract of soursop leaf flour, concentration, botanical insecticide

Abstract

Soybeanis a source of vegetable protein and the basis of variety of processed products. Chrysodeixis chalcites is one of the major pests in soybean plant. Currently efforts in controlling C. chalcitesstill use synthetic insecticide that can have negative impacts. Reducing the effects caused by synthetic insecticide, therefore need alternative in pest control techniques such as use local entomopathogenic fungi Cordyceps militaris. The purpose of this research is to get concentration of local entomopathogenic fungi C. militaris which best in control C. chalciteson soybean plants. Research prepared using completely randomized design (CRD) with 5 treatments and 5 replications. The treatment used is some concentration of local entomopathogenic fungi C. militaris consists of 5 treatments are 20 g/l of water (45,2 x 107 kon/ml), 30 g/l of water (67,8 x 107 kon/ml), 40 g/l of water (90,4 x 107 kon/ml), 50 g/l of water (113,0 x 107 kon/ml), and 60 g/l of water (135,6 x 107 kon/ml). The results showed concentration of local entomopathogenic fungi C. militaris 60 g/l of water (135,6 x 107 kon/ml) is the best concentration because can to provide the fastest time to early death for 45,4 hours, lethal time 50 (LT50) for 113,8hours, and caused total mortality 84% for 168 hours. The exact concentration to control 95% of the population of C. chalcites is 18,59% or 185,9 g/l of water. Keyword:Local entomopathogenic fungi Cordyceps militaris 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).

Abstract

Upland rice prouction (Oryza sativa L.) in Riau Province was lower than the   previous year. One of the main constraints of upland rice is one of which is rice bug pest attack (Leptocorisa acuta T.). Eco-friendly pest  controls are offered using pestiside vegetables of gadung tuber extract (Dioscorea hispida Dennst). The aim of  the study was to obtain the concentration of  gadung tuber extract which was effective in controlling the stink bug pest on upland rice plants in the field. The research has been implemented in the experimental garden (green house), Faculty of Agriculture, University of Riau which from January to April 2018. The research is prepared using a completely randomized design (CRD) with 5 treatments and 4 replictions, ie the concentration of  gadung tuber extract 80,85,90,95, and 100 grams/liter water. The observed Parameters are, morphology changes and behavior, the start time of the death (hours), lethal time 50 (hours),  daily mortality (%), total mortality (%), temperature and humidity.  The results showed that the concentration of 90 grams/liter of water was an effective concentration for controlling rice bug pest control with an initial death time of 3.50 hours, lethal time 50 15.25 hours after application and a total mortality of 85%. Keywords: Upland rice plants (Oryza sativa L.), Rice bug (Leptocorisa acuta T.), Vegetable pesticides, Gadung tuber extract (Dioscorea hispida Dennst),

Abstract

The objective of this  research  was to get the best botanical insecticide extract to kill golden snail pest on paddy plant. The study arranged experimentally using Complete Randomized Design (CRD)  consist of 4 treaments and 5 replications until get 20 experiment unit.  Every unit was infected by 8 golden snails pest with 30 days old. The treatment was from some botanical insecticide with 10 % concentration  consist of forest betel leaf extract, neem leaf extract, soursop leaf extract, and Titonia diversifolia leaf extract. The parameters those obsevered were  early death  (hour), lethal time 50   (hour),  daily mortality (%), total mortality (%),  temperature and humidity daily on study site. The result showed that neem leaf extract with 10% cocentration have the best  ability and effective to control P. canaliculata with early death 15,2 hours, LT50  24,60 hours and total mortality until 95%. The soursop leaf extract and Titonia diversifolia leaf extract with 10% concentration also effective because can kill more than 80% P. canaliculata.

Abstract

Palm oil plant is one of plantation crop that grown by people of Indonesia, especially Sumatra (Riau). Setora nitens is one of the major pests in palm oil plantations. Management control to decrease the Setora nitens by using synthetic insecticides. Reducing the effects caused by synthetic insecticides, therefore need alternative in pest control techniques such as use organic insecticide derived from Piper aduncum L. The purpose of this research is to get Piper aduncum L. leaf powder extract concentrate that effective to control Setora nitens at palm oil plantations. This research was carried out experimentally by using Completely Randomized Design consisting of 5 treatments with 4 replications. The treatment consisting five level: SRH 0 (no concentration), SRH 1 (concentration of 25 g/liter of water), SRH 2 (concentration of 50 g/liter of water), SRH 3 (concentration of 75 g/liter of water) and SRH 4 (concentration 100 g/liter of water). Results showed that the concentration of 100 g/liter was able to kill Setora nitens by 45% and this has not been effective in controlling caterpillars Setora nitens because not reach 80%. The best concentration to kill 95% of the population of Setora nitens is 206% or 2.06 kg/l of water. Piper aduncum L. leaf powder extract has not been effective in controlling caterpillars Setora nitens at palm oil plantations.
