Abstract

Nezara viridula is one of the major pests which attack  bean (Vigna sinensis) plants. Crop damage due to  attack of N. viridula depend on the number of pests, the availability of nutrition as well as  biotic and abiotic factors. The useof synthetic insecticides continuously with inappropriate dose and time application cause negative impact on the environment, therefore the use of insecticide plant is one alternative to reduce pesticide dose. The purpose of this study was to determine the concentration of papaya leaf extract and verify application method which promote  mortality of N. viridula ninfa. Experiment was set up in completely randomized block design with four treatments, i.e 40 g/100 mL of water, 50 g/100 mL of water, 60 g/100 mL of water and 70 g/100 mL of water. Observations were made on early symptoms of toxocity, the percentage of mortality, mortality rate and advanced stages of N. viridula. The results showed that application of papaya leaf extract with at 70 g / 100 mL of water through feed or contact caused 100%  mortality of N. Viridula,  with  mortality rate of 4.75 days and 5.50 days. It is sugeested that  vegetable-based insecticide could be used to decrease N. viridula attack on string bean pod.

Abstract

Efforts to increase crop production often faced difficulty with pests and diseases. The use of high yielding varieties can be an alternative control. This study aimed to determine the population and intensity of pest damage Plutella xylostella on five varieties of cabbage (Brassica oleraceae L.). The experiment was conducted in the village Waipirit in October 2012 until January 2013. The study was designed using a randomized block design with five treatments, namely cabbage as the Grand 11, KK-Cross, Green Coronet, Green Hero, and Investor. The results showed that Investors were varieties that were resistant to pests Plutella xylostella, indicated by low population groups such as eggs 2.75, 16.55 tails larvae and 1.95 tails pupae, and the low intensity of leaf damage 28.51% which was classified medium.

Abstract

There are many methods to manage plant pests and diseases. One method that is always used by farmers is chemical control using synthetic pesticides. Utilization of synthetic pesticides inappropriately in terms of kind, target, dose/concentration, technique and time can be unsafe to the environment as well as the consumers. The objective of this research was to determine pesticide residues on fresh vegetables in the central market of Ambon city.  The vegetables being sampled were spinach (Amarantus indica), water cresant (Ipomoea aquatica), green mustard (Brassica juncea) and  long bean (Vigna sinensis) collected from Mardika and Passo local markets, Ambon City. Residue analysis was conducted at the Testing Laboratory of the Agricultural Post Harvest Research and Development Board of the Ministry of Agriculture, Bogor (Laboratorium Pengujian, Balai Besar Penelitian dan Pengembangan Pasca Panen Pertanian, Kementrian Pertanian, Bogor).  The results showed that the residues of Organochlorine (Chlorinated Hydrocarbons), Organophosphate, Carbamate and Pyrethroid were detected on sampled vegetables from central marketing at Ambon City. The residues of these classes of synthetic pesticides were detected in the form of Heptachlor, Aldrin, Endosulfan, Lindane, Chlorpyrifos, Profenofos, Diazinon, Monocrotophos, Parathion, Carbofuran, and Cypermethrin.  The residues detected were below Maximum Residue Limit (MRL) based on SKB of the Minister of Health and the Minister of Agriculture (Menteri Kesehatan dan Menteri Pertanian) No. 881/MENKES/SKB/VIII/1996 and No. 711/Kpts/TP270/8/96, and The Regulation of the Minister of Agriculture (Peraturan Menteri Pertanian) No.27/Permentan/ PP.340/5/2009

Abstract

Plutella xylostella L. (Lepidoptera: Plutellidae) is one of the major pests on chinese cabbage (Brassica pekinensis). It damage the  2-6 week old plants. Larvae damage  crops by biting, chewing and then eating the lower surface of the leaves. The leaves will become transparent white, severe damage leaves behind only leaf bone. Papaya leaf (Carica papaya) could be used as a pesticide for crops because it contains substances that can inhibit eating even to kill insects pests. The purpose of this study was to verify the efficacy of  the papaya leaf extract against Plutella xylostella. The study was conducted in the laboratory of Plant Pests Faculty of Agriculture, Pattimura University. The design used was a completely randomized design with four papaya leaf extract concentration at 3 instar larvae through the  contact and stomach poison test. Observations were made on the early symptoms of poisoning, the percentage of larval mortality, and further Plutella xylostella stadium. The results showed that the highest mortality in the treatment of stomach and contact poison was occured at a concentration of 40 g/100 ml of water by 100%, while the lowest mortality at a concentration of 10 g / 100 ml of water, respectively by 35% and 20%.
