Definitions
- the present invention relates to a herbicide comprising a microorganism having a weed control ability and at least one of vegetable oil, mineral oil and silicone as an active ingredient, and a herbicide using the herbicide.
- Collego which uses spores of the pathogenic microorganism Coll etotrichum gloeosporioides f. Sp. Aeschynomene, is commercially available for controlling legume weeds in soybean fields.
- Lu-boa No.2 which uses Colletotorichum gloeosporioides for controlling soybean parasitoids in China, and Colletotrichum gloeosporioides f.sp. BioMal (Pilom Bios) as an active ingredient is commercially available.
- spores that can be dried can be easily formulated as powdered wettable powders, etc.
- An object of the present invention is to solve the problems of such conventional herbicides and herbicidal methods. Specifically, the present invention does not require dilution with water at the time of use and has excellent storage stability. It is to provide a microbial herbicide.
- the present inventors have completed the invention based on the finding that a composition comprising oils such as vegetable oil, mineral oil, and silicone is effective in controlling weeds in paddy fields, and filed an application earlier (Japanese Patent Application Hei 5-333087).
- the present inventors have further studied the oils, and found that microorganisms can survive for a long time in these oils, and that these oils have increased the ability to control weeds possessed by the microorganisms. It has been found that the present invention can be improved, and the present invention has been completed.
- a first aspect of the present invention is a herbicide characterized by containing a microorganism having a weed controlling ability and at least one of vegetable oil, mineral oil and silicone as an active ingredient.
- the microorganisms having the ability to control weeds used herein include microorganisms belonging to Exerohilam II and Calvularia II.
- Exeguchi Hiram monoceras can be exemplified as a preferable microorganism.
