Compositions and methods for controlling a plant pest or for treating or preventing plant disease are provided. Such compositions and methods comprise a bacterial strain that controls one or more plant pests or that improves at least one agronomic trait of interest in a plant. The bacterial strain can be used as an inoculant for plants. Methods for controlling a plant pest, for growing a plant susceptible to a plant disease, and for controlling plant disease on a plant susceptible to the plant disease are provided. Methods for improving at least one agronomic trait of interest in a plant are also provided.

The application provides an enzyme immobilization carrier and a preparation method thereof, an immobilized enzyme and a preparation method thereof. The above enzyme immobilization carrier is obtained by an amino modification or a cyanuric chloride modification of super-crosslinked polyvinyl alcohol. The use of the enzyme immobilization carrier provided by the application may effectively improve the stability and reusability of the immobilized enzyme. Moreover, due to the use of the form of enzyme covalent linkage, compared with an embedding method, the preparation method is no need for chemical reagent immersion and the like, it is beneficial to maintain the own activity of the enzyme, and promote the immobilized enzyme to have the better activity while the stability and reusability are kept.

The present invention relates to the potentiating effect of the association of botanical extract and Bacillus ssp. as a bionematicide agent and its surprising potential effect in promoting plant growth in a single product achieved by a distinguished industrial process. The industrial process of inducing the formation of Bacillus spp. endospores by osmotic stress of vegetative cells in a culture medium during bacterial growth is what allows the mixing of Bacillus spp. and botanical extract, since there is an incompatibility between the Bacillus species themselves and the botanical extract, both in the vegetative phase of the microorganism. Finally, synergy between the active ingredients, microbial cells and allicin, activate the bionematicide and growth-promoting function of the disclosed biotechnological composition.

There is described herein a consortium of micro-organisms comprising, consisting or consisting essentially of Rhizobium spp., Bacillus spp., and Pseudomonas spp.
