- the present invention provides a new effect that has no adverse effect on cultivated crops, has no risk of environmental pollution, and exhibits excellent effects even when used in a very small amount.
- the purpose of the present invention is to provide a regular germination inhibitor.
- the present inventors have found that a pigment produced by a fungus belonging to the genus Mucuna lucidum, which first occurs in fallen hardwoods and causes them to rot and turn blue-green, inhibits the growth of algae. Although it was found that it had an action, it proposed a plant growth inhibitor containing the active ingredient as an active ingredient, but as a result of further studies, it was found that it exhibited an excellent germination inhibitory action on many plants. The present invention has been made based on this finding.
- the present invention provides a plant germination inhibitor comprising, as an active ingredient, a pigment produced in a woody part by a bacterium belonging to the genus Oryza sect.
- a method for controlling the formation of plant tissue comprising spraying the plant germination inhibitor during the germination period of the plant to the area where the plant is growing, thereby suppressing the germination of the plant and preventing the formation of rhizome tissue.
- the above-mentioned plant germination inhibitor is sprayed on the symbiotic area of at least two types of plants, and the formation of rhizome tissue of plants other than the required cultivated plants is selected by utilizing the difference in germination conditions of each plant.
