The invention concerns novel nitrification inhibitors.

The present disclosure provides an integrated rice-crayfish-oriental river prawn planting-breeding method. The method includes the following steps: stocking crayfish postlarvae in a paddy field as an integrated rice-crayfish-oriental river prawn farming area from February to March, catching and marketing the crayfish from May to June; planting in mid-June, sun-drying rice seedlings in the field in late June, cleaning and disinfecting a ring ditch surrounding the paddy field, and transplanting some aquatic plants; stocking oriental river prawn postlarvae in early July; harvesting ripe rice in late October; and catching and marketing the oriental river prawns in November. On the premise that the rice planting area is not reduced, the present disclosure realizes the effective expansion of time and space of the paddy field and improves comprehensive benefits of rice-fish farming in the form of integrated rice-crayfish-oriental river prawn planting-breeding.

The objective of the invention is to provide a plant activator having a resistance to the wash-off and a superior handleability, transportability and storage stability. A powdery plant activator comprising, at least one compound selected from an oxo fatty acid or a derivative or a salt thereof and a hydroxy fatty acid or a derivative or a salt thereof, and an unsaturated fatty acid (excluding an oxo fatty acid and a hydroxy fatty acid).

This invention relates to methods and materials for providing a benefit to a plant by associating the plant with a complex endophyte comprising a host fungus further comprising a component bacterium, including benefits to a plant derived from a seed or other plant element treated with a complex endophyte. For example, this invention provides purified complex endophytes, purified complex endophyte components such as bacteria or fungi, synthetic combinations comprising said complex endophytes and/or components, and methods of making and using the same.

An agricultural field management system includes a map data recording section having a field map layer for recording field map data, a field work data recording section having a machine-type-specific field work layer for recording field work data generated for each work implemented by various kinds of farm work machine on the field, a data management section 60 for executing data management on the field map data and the field work data at a common coordinate position, and an evaluation section 70 for effecting farming evaluation of the field based on the field work data.

The present invention relates to the use of a herbicide-tolerant protein, wherein the method for controlling weeds comprises applying a herbicide containing an effective dose of tribenuron-methyl to a plant growth environment where at least one transgenic plant is present, wherein the transgenic plant comprises a nucleotide sequence encoding a thifensulfuron hydrolase in its genome, and compared to other plants without the nucleotide sequence encoding the hydrolase, the transgenic plant has reduced plant damage and/or an increased plant yield. The present invention discloses for the first time that a thifensulfuron hydrolase can show a high tolerance to a tribenuron-methyl herbicide, plants containing a nucleotide sequence encoding the thifensulfuron hydrolase are strongly tolerant to the tribenuron-methyl herbicide and can at least tolerate 1-fold field concentration, and thus the hydrolase has broad application prospects in plants.
