Oryza sativa L. can be called an important commodity because it is used as a staple food. Farmers in cultivating rice expect high yields, but there are obstacles that cause yields to decline, namely the attack of the Brown Stem Planthopper (BSP) (Nilaparvata lugens Stal.) which can lead to crop failure. Farmers controlling N. lugens still use insecticides. Control by using insecticides is known to have a negative impact on users and the environment and can cause resistance, resurgence and residue. One of the safe controls is the use of Beauveria bassiana as an entomopathogenic fungus. This study was conducted to determine the effectiveness of B. bassiana cultured on various media in controlling WBC attacks. The design used was a Completely Randomized Design (CRD) with 6 treatments, namely control treatment without B. bassiana, control with B. bassiana grown on PDA media, B. bassiana grown on corn media, and B. bassiana growing on media. grown on rice media, given B. bassiana grown on bran media, given B. bassiana grown on husk ash and repeated 4 times. Observations were made after one application by observing mortality (mortality) every 24 hours for 7 days. The results of the observation that the highest mortality percentage was found in the corn media treatment reaching 47.50%, rice media 40%, bran media 18.75% while the lowest was found in the husk media, namely 15%.

Plant Pest Organisms (PPO) that have recently become a problem in corn cultivation are Fall Armyworm (FAW) or the armyworm Spodoptera frugiperda J. E. Smith. The damage of S. frugiperda on sweet corn and feed is thought to be different and is not yet known. This study aims to determine the level of destruction of S. frugiperda on sweet corn and feed with control treatment of biological pesticides on papaya leaves and garlic, 30 ml/l water, 40 ml/l water, and 50 ml/l water. This study used a completely Randomized Design (CRD) with two factors. Corn varieties and concentrations of vegetable pesticides. The treatments used in this study were water control, chemical control, and three treatments of biological pesticide concentration with four replications. The results of observations 1-3 (age 0-2 weeks after planting/ WAP) have not found an attack, occurred on the study to 4-7 (age 3-6 WAP). Pesticides of papaya leaf and garlic affected the destructive power of S. frugiperda, where the concentration factor on the incidence of attack and attack intensity had a very significant effect, an interval of the variety factor had to make a difference on the incidence of attack but did not significantly affect the potency of the attack. The 50 ml/l concentration treatment on sweet corn and feed varieties was the best in suppressing the percentage of attack (12.50; 23.40%), attack intensity (5.92; 8.00%), and damage to the cob (1.79); 4.79%).

Red chili (Capsicum annuum L.) is a commodity that has high economic value, but the potential loss experienced in chili cultivation is also quite high, because chili is quite vulnerable to fruit fly pests. This study aims to determine the response of fruit flies to the use of pheromones derived from various kinds of fruit peels and flesh added with yeast (organic pheromones). This research took place on chili farmers' land located in the village of Tambak Langsat, West Ulin Platform, Banjarbaru City. This study used a randomized block design (RBD) with 11 treatments including the control. The results showed that the treatment given organic pheromones was able to trap fruit flies. Of all the pheromones that were most effective at getting lots of fruit flies was the chili pheromone (0.2 ml) with a catch of 25 individuals and for organic pheromones that were less effective was the mango pheromone (0.2 ml) with a catch of 4 individuals. The type of fruit fly B. dorsalis dominates of the four species with the Diversity Index (H´) of fruit flies being classified as moderate, namely 1.1082, the Dominance Index (D) being high 1 and for fruit flies dominating B. dorsalis.

C. kyllingia is an annual weed that can cause problems because it can reduce the quantity and quality of cultivated plant production, so this weed needs to be controlled. Weed control with synthetic herbicides is currently more popular because its effectiveness can be seen more quickly. However, if synthetic herbicides are used for a long period of time, they will affect soil conditions. Therefore, an alternative weed control using liquid smoke from empty oil palm fruit bunches (TKKS) is needed. The research aims to determine the potential of TKKS liquid smoke in controlling the growth of sedge weed (C. kyllingia). The design used a 1 factor Completely Randomized Design consisting of 5 treatments and 5 replications with liquid smoke concentrations of 0%, 8.3%, 16.6%, 25% and 33.3%. Research shows that TKKS liquid smoke has the potential to be used as a natural herbicide because it has an effect on suppressing the growth of the C. kyllingia weed. The best concentration that can suppress weed growth is 33.3% liquid smoke.
