Abstract

Brown planthopper (BPH) is a major pest on rice plants that can cause hopperburn and crop failure. The study aimed to determine the level of BPH attack on several local rice varieties in the Pasaman Regency. This research was conducted in a greenhouse, Faculty of Agriculture, Universitas Andalas, using a completely randomized design (CRD), with five treatments and five replications. The treatments were four different rice varieties from Pasaman and control (Siganteng, Pulau Batu, Mundam Kuning, Mundam Putih, IR 42). BPH was infested when the rice was five days after sowing. Observation parameters were the percentage and the intensity of the attacks. Observations were done until 15 days after infestation; after the IR 42 variety died 90%. The results showed that the attack rate of BPH on rice varieties from Pasaman was moderate. The lowest percentage of attack occurred in the Mundam Putih variety (94%), while the intensity of the attack was not significantly different from other varieties.

Abstract

Mangkokan leaves (Nothopanax scutellarium Merr) have been used to control golden snail (Pomacea canaliculata Lamarck) in several preparations. This research aimed to study the most effective preparation of the mangkokan leaf extract to control the golden snail. The research was conducted in the Insect Bioecology Laboratory and agriculture field in Batu Busuak Village, Pauh District, Padang City, from March to April 2021. This study used a Completely Randomized Design (CRD) consisting of five treatments and five replications. The treatments were several preparations of mangkokan leaves with a concentration of 5 g/l: control, fresh, boiled, sun-dried, and oven-dried. The observed variables were mortality of the golden snail, the weight of feed consumed, and the decrease in the eating activity of the golden snail. The result showed that botanical molluscicide from mangkokan leaves preparation by oven-dried and fresh were the two most effective in controlling the golden snail because they caused 100 % mortality of the golden snail, reduced the feed number consumed, with decreasing in feeding activity of 54.91% and 52.94%.

Abstract

Integrated Pest Management (IPM) is a pest control method that combines several control techniques by considering ecological, economic, and sociological consequences. Management efforts with IPM principles can be conducted by cultivating healthy plants and entomopathogen application. This study examined the IPM package's success for controlling fall armyworm (Spodoptera frugiperda) in maize field. This research was conducted in a farmer's maize plantation in the West Pasaman District from August to December 2021. The study used a Randomized Block Design (RBD) which consisted of three treatments and five replications. The treatments were different cultivation techniques using IPM, Non-IPM, and control. The variables observed were the population of S. frugiperda (individual/plant), attack rate (%), attack intensity (%), cob weight (g/cob), and farming cost (IDR). The results showed that the IPM and Non-IPM maize cultivation techniques had no different effect on S. frugiperda, especially survival stage, attack rate, intensity, and yield. However, this effect was higher than the control. In addition, the economic benefits of cultivation with IPM were higher than non-IPM. Therefore, this IPM package can be recommended for controlling S. frugiperda because it is also economically profitable and environmentally friendly.
