The parameters developed in organic farming are the use of vegetable pesticides and compost and liquid organic fertilizer. Some research has been done but it needs deeper research to get the right product. The purpose of this study was to determine the inhibitory activity of Piper caninum extract against the fungus Pyricuaria oryzae causing blast disease in rice, and to find out how much the impact of compost on increased crop yield after being combined with the extract. This research is a field research located in the village of Senganan, Penebel Tabanan Bali. With the following treatment Fo = control (100% soil). F1 = (soil 90% + compost 10% + extract 0.5%). F2 = (soil 80% + compost 20% + extract 1%) F3 = (soil 70% + 30% + extract 1.5%). F4 = (soil 60% + compost 40% + 2% extract), do repeat 4 times. The results showed that P. caninum extract effectively inhibited blast disease and could reduce the intensity of blast disease. The combination with compost can significantly increase yields (67.62%), reduce empty grains, and increase rice size.

Field experiments were conducted to investigate methods of controlling red rice (Oryza sativaL. ♯ ORYSA) in drill-seeded rice (O. sativa). Treatments included the rice cultivar ‘Mars', coated with calcium peroxide (CaO2) at 40% (w/w) and a crop protectant, R-33865 (O,O-diethyl-O-phenyl phosphorothioate) at 0.5 and 1% (v/w). Molinate (S-ethyl hexahydro-1H-azepine-1-carbothioate) at 6.7 kg ai/ha was applied preplant incorporated (ppi). The land was flooded (2.5 to 5 cm deep) after seeding with rice (100 kg/ha, 2.5 cm deep), and the water was maintained throughout the growing season. CaO2, with or without molinate, increased rice grain yield 50% and increased rice culm density fivefold above untreated rice. Molinate applied ppi controlled 96% of the red rice. Rice seed coated with only CaO2or with CaO2plus R-33865 at 0.5%, each combined with ppi molinate, produced 5690 and 6030 kg/ha of grain, respectively. These high yields were associated with red rice control by molinate and good stands of rice provided by O2supplied by CaO2. R-33865 applied to rice seed at 1% (v/w) injured rice by reducing rice culm densities 41%, compared with rice without protectant.

Reciprocal controlled crosses were made in the greenhouse between Gulfmont rice transformed with the bialaphos resistance (BAR) gene and red rice and BAR-transformed Koshihikari rice and red rice to assess the inheritance of glufosinate resistance. All F1 plants were resistant to 2.2 kg ai/ha glufosinate. Ammonia accumulation as a measure of glufosinate resistance in the F1 hybrids was assayed at 4 and 8 days after treatment (DAT). Ammonia accumulation in hybrids 4 DAT was similar to glufosinate treated, transformed rice, while treated nontransformed plants accumulated 14 to 23 times more ammonia compared with the hybrids. The nature of inheritance of glufosinate resistance in F2 rice plants was studied by a glufosinate dip test, a spray test, and ammonia assay. All three tests confirmed that glufosinate resistance, as influenced by the BAR gene, segregated in a 3 (resistant): 1 (susceptible) ratio.

Two field experiments were conducted from 1986 to 1988 to determine efficacy of herbidices and plant growth regulators for red rice control and suppression in water- and drill-seeded rice. Molinate applied PPI with fenoxaprop applied at panicle initiation (PI) of rice controlled 94 and 86% of red rice in water- and drill-seeded rice, respectively, compared with 79 and 49%, respectively, for molinate PPI alone in the two cultures. Although this treatment injured rice slightly (< 30%), rice so treated produced high yields with improved grain quality. Sequential treatments of molinate PPI followed by sethoxydim applied at PI or amidochlor applied at > 90% heading produced comparable rice yields with improved red rice control or suppression and grain quality in both cultures, compared with PPI molinate. Drill-seeded rice treated with molinate PPI followed by fenoxaprop applied at late boot or MH (maleic hydazide) applied 7 d after heading produced higher yield than rice treated with molinate PPI.
