Abstract

This document relates to the use of jasmonate or related compounds in combination with crop input products (e.g., herbicides, pesticides, bioactives or biologicals, seed treatment components, semiochemicals, and the like) to induce biodefense activity in plants. Also provided are compositions comprising a jasmonate or related compound with one or more crop input product.

Core Innovation

The disclosure describes compositions and methods that use cis-jasmone together with Bacillus subtilis to increase plant biodefense activity. The invention is directed to applying these components to a plant, a plant propagule, or soil so that the plant exhibits an increase in plant health, quality, or yield.

A central aspect of the invention is that cis-jasmone and Bacillus subtilis are provided as a composition and can optionally include a crop input product. The crop input product is selected from fungicides, herbicides, insecticides, nematicides, and acaricides, and the approach integrates plant biodefense-inducing chemistry with crop input products to improve the performance of those inputs.

The disclosure also describes method embodiments that apply the cis-jasmone and Bacillus subtilis composition through drench or foliar application, or to a plant propagule as an additive prior to, during, or after planting. Additional embodiments include inducing a biodefense activity through applying the composition at multiple stages of plant growth, combining seed application with post-emergence application, and applying the composition as a mixture to reduce pest infestation.

Claims Coverage

The independent claims cover five inventive aspects, each centered on cis-jasmone combined with Bacillus subtilis and applied to a plant, plant propagule, or soil.

Across the independent claims, the inventive coverage is consistently anchored in cis-jasmone combined with Bacillus subtilis and applied to a plant, plant propagule, or soil. The claims differentiate outcomes as increased effectiveness of a crop input product, induction of biodefense activity, and reduction of pest infestation, and they specify application modalities and timing such as drench, foliar, plant propagule additive timing, multiple stages of plant growth, and seed plus post-emergence application.
