Ecological vegetable growers often struggle with pests and disease pressure. There is anecdotal and observational information around the use of organic foliar sprays, but quantitative data is lacking. While nutrient foliar sprays can be expensive, the cost could be less than time and space cost associated with succession planting needed to manage disease pressure. With the goal of minimizing succession planting and field space while maximizing harvestable yield, Angie tested the efficacy of a nutrient foliar spray to maintain health of her cucurbits.
