Marigold flower has many benefits in many aspects of life in Bali Island (Indonesia) including often used in religious ceremonial activities. For controlling plant pests and diseases, marigold is planted on the sidelines or on the edge of a land as an attractant crop to invite natural enemies and marigold also can produce certain substance which can reduce the incidence of nematode. In inducing mutagenesis in this research, the seeds of marigold were soaked in solution of colchicine with hydrogen peroxide as its solvent. The results of this research indicated that the treatments caused the formation of chlorophyll mutant and an increase in the length of flower diameter. Both the control and treated plant samples were attacked by leaf miner, giant land snail, virus-like disease and botrytis flower blight disease.

Weed is a part of OPT (Plant Disturbing Organism) besides plant pests and diseases. Weeds cause damage slowly, due to competition with cultivated plants to obtain nutrients, water, light, CO2 and growing space. Weeds are harmful and disturbing so humans try to control them. From various aspects of life both health, aesthetics, environment and the field of farming, weeds can interfere with natural habitat and beauty. Weeds are always considered as exotic plants or migrants that are invasive and potentially disrupt the local environment. However, not all weeds play a negative and potentially disturbing role. Weeds are also able to provide a comfortable habitat for the development of natural enemies in the agrosecosystem. Refugia is a weed plant area that can provide shelter, food sources or other resources for natural enemies such as predators and parasitoid. Efforts to conserve natural enemies using refugia are one alternative to controlling plant pest organisms such as pests. Keywords: Refugia, Weeds, Conservation, Natural Enemies
