Compositions and method for producing a systemic acquired response (SAR) in plants. The resulting SAR may improve plant health and corresponding yields. In an example, the composition comprises a base solution and an effective amount of chitosan (Aspergillus niger) (e.g., in an amount of about 0.04 wt% of the composition). The base solution may include organic material, vitamin K compound, and nitrogen. Additionally or alternatively, the composition may include adding to the composition at least one of potassium, phosphorus, or an acidic organic polymer. Still further, the composition may include a micronutrient comprising at least one of boron, calcium, copper, iron, manganese, sulfur, silicon, or zinc. The composition may be applied as a foliar spray or used to irrigate the plant. |
