Provided are bioactive compositions and metabolites derived from Bacillus and particularly Bacillus megaterium cultures responsible for controlling pests as well as their methods of use for controlling pests. Further provided are pesticidal Bacillus megaterium strains.

Compositions are provided that include a new Bacillus thuringiensis strain designated RTI545 for use in benefiting plant growth and controlling plant pests. In particular, the RTI545 strain is useful for controlling plant nematode, insect and fungal pests. The compositions include plant seeds coated with the RTI545 strain. The compositions can be applied alone or in combination with other microbial, biological, or chemical insecticides, fungicides, nematicides, bacteriocides, herbicides, plant extracts, plant growth regulators, or fertilizers. In one example, enhanced growth and insect control are provided by delivering at the time of planting a combination of a chemical insecticide such as bifenthrin and a liquid fertilizer to plants or seeds treated with RTI545.

The present invention relates to an aqueous suspension concentrate composition useful in agriculture to control pests harmful to commercial crops, comprising(i) cyclobutrifluram; (ii) 25 to 125 gram/liter of a vegetable oil; and(iii) 25 to 125 gram/liter of an ethoxylated fatty alcohol.

The invention concerns (i) the use of a red alga extract as nematostatic agent against nematodes and/or as a nematicidal agent against nematodes and (ii) a method for treating soil to promote growth of a plant by reducing nematodes access to the roots of said plant or by eliminating nematodes present in said soil, said method comprising supplying said soil with a red alga extract.
