Abstract

The use of plant extracts and predators is an alternative for pests control and disease that are safe for the environment. The aim of this research is to find out plant extracts and predators in controlling major pests and diseases effectively. The research was conducted at the Indonesian Vegetable Research Institute at an altitude of 1250 m above sea level from June to December 2018.The design used was Randomized Block Design and was repeated 4 times. Tried treatment: (A). Spinach (Amaranthus spinosus) extract. (B). Four o'clock flower (Mirabillis jalapa). (C). Given the predator Menochillus sexmaculatus at the beginning of planting. (D). Synthetic insecticide with the active ingredient Immidaclorprid. (E). Spinach spinach extract + predator. (F). Four o'clock flower extract + predator. (G). Spinach Extract + Predator + Insecticide. (H). Four o'clock flower + predator + Insecticide. (I). Control. Research results: (1). Plant growth is not affected by treatment. (2). Phytotoxic symptoms due to treatment of plant extracts did not appear in plants. (3). The treatment of giving predatory M. sexmacullatus at the beginning of planting + insecticide, combination of spinach thorn extract + predator + insecticide, combination of four o'clock flower extract + predator + insecticide, increased its efficacy against chili pests and diseases and had an impact on low fruit diseases and increased yields.

Abstract

The expired status is addressed to the seeds that have exceeded the recommended planting period by the producer, while invigoration is the improving process of a vigor or performance of the deterioration seeds. The research purposes were to find out the best composition of kind and immersion time of a flora material extract that could improve physiological quality of the expired chili seeds. The research was conducted at the Seed Laboratory of Indonesian Vegetable Research Institute (IVEGRI), Lembang from Mei 2018 to December 2018 using a Completely Randomized Design (CRD) of 11 treatments which was repeated three times. The treatments consisted of: (1) Control (expired seeds without treatment); (2) Green coconut water 15% + Incubation 24 hours; (3) Ambon banana extract 15% + Incubation 24 hours; (4) Ambon banana extract 15% + Green coconut water 15% + Incubation 24 hours; (5) Cucumber extract 15% + Incubation 24 hours; (6) Green coconut water 15% + Incubation 48 hours; (7) Ambon banana extract 15% + Incubation 48 hours; (8) Ambon banana extract 15% + Green coconut water 15% + Incubation 48 hours; (9) Cucumber extract 15% + Incubation 48 hours; (10) Green coconut water 15% + Incubation 72 hours; (11) Ambon banana extract 15% + Incubation 72 hours. Then, the incubated seeds were germinated using top of paper (TP) method by the Copenhagen Tank apparatus. The results showed that the use of green coconut water 15% + incubation 24 hours (treatment No. 2) or cucumber extract 15% + incubation 48 hours (treatment No. 9) could improve viability and germination speed performance in range 12.67-13.33% and 3.85-5.10%/etmal respectively of the expired chili seeds with viability condition less than 75.00%.
