Abstract

Effectiveness of In Vitro Inhibitor Effects of Botanical Pesticides on Growth of Some Pepper Seed Born Pathogens ColoniesABSTRACT. Recently, the use of bio-pesticides significantly increases to control some plant diseases due to the drawback of chemical pesticides to environment. Some experiment have been done to evaluate the effectiveness of some vegetable oil as bio-pesticides to inhibit the colony growth of pepper seed born pathogens in vitro. Various concentrations of vegetable oil were added onto potato dextrose agar medium (PDA), afterward, the growth of pathogen colony in treatment was compared to control (medium without vegetable oil). Evaluation was done in certain period time depend on the growth of every pathogen colony Among the vegetable soil tested, clove oil and Andropogon nardus oil showed a very high inhibitory effect to colony growth of P. capsici, C. capsici, F. oxyporum, R solani, and S. rolfsii. Concentration 0.01% of those oil already inhibited the colony growth of all pathogens more than 75%, with the exception of A. nardus oil which required 0.03% to inhibit C. capsici colony. Concentration of clove and A. nardus oil above 0.01% completely inhibited growth of all pathogens colonies, except for F. oxyporum. Meanwhile, others vegetable oil like Curcuma xanthorrhiza, Kaempferia galangal, Kaempferia pandurata, and Curcuma domestica oil have a low inhibitory effect on growth of all pathogens colonies. To get inhibitory effect more than 75% on the growth of colonies, those vegetable oil needed concentration higher than 0.02%. However, K. galangal and C. domestica required 0.02% oil concentration for P. capsici and S. rolfsii, respectively.

Abstract

The Parasitism Level of Various Egg Parasitoids Associated with Nezara viridula L. on Soybean PlantationABSTRACT. It is well known that the presence of various egg parasitoids on the green stink bug, Nezara viridula, can decrease the population of this insect pest on soybean plantation. A research has been conducted to observe the parasitism level of various egg parasitoids associated with N. viridula on different stages of soybean plantation. The plant stages used were 4-5, 6-7, 8-9, and 10-12 weeks after planting (WAP), with 6 experimental plot for each stage, and 5 plants for each experimental unit. Three pairs of N. viridula adult then were relased onto each plant which was covered by the gauze cage earlier. When egg were laid, the cage was taken out leaving 2 eggs rafts per plant. These N. viridula eggs then were exposed to parasitoid for three days, before taking them all to the laboratory. The observations were done on the parasitized eggs. The result showed that different stages of soybean plants significantly affected the parasitism level of various egg parasitoids, with 26 to 46% parasitism level. Up to 71.8% of parasitize egg successfully became adult parasitoids. There were four different Hymenoptera egg parasitoids found associated with N. viridula, namely Telenomus sp. (Scelionidae), Gryon sp. (Scelionidae), Mycroteris sp. (Encyrtidae), and Anastatus sp. (Eupelmidae). Due to its abunden (91.5%) on soybean plantation, and its fair sex ratio, Telenomus sp.is believed to have a great potential for future development as a biological control agent on the green stink bug, N. viridula.

Abstract

The Competitive of Soybean Used as Dessicant with Paraquat and Glifosat Herbicide on Stress of WeedsABSTRACT. Herbicide might be use for desicant to increase soybean seed quality at rainy season, however not all herbicide can be used as dessicant. Seed with a better quality will growth faster than weed will, they will form leafy coronet that shaded the weed and be able to compete against to the weed. The experiment was conducted during rainy season at PT Syngeta-Cikampek, West Java, started from November 2003 to March 2004. This experiment that was the second experiment was arranged in two-factor randomized block design with two replications. The first factor was the 21 seeds generated from dessicacy test in experiment 1; the second factor was the invasion status of weed that consist of weed invated and weed free. The observed responses includes the weed’s characteristics that consist of dominant value ratio and the soybean’s response that consist of the height of the plant, the length of the root, the weight of 100 seed. The data was analyzed by Percentage Change Test, Least Significant Increase (LSI) Test, Stres Tolerant Index (STI) Test and continued by Directed STI, The result shows that the seed generated from paraquat herbicide dessicacy at dose of 0.4 kg a.a ha-1 applicated at R2 are more superior than other seed treated by any oyher treatment.
