Pesticide-free strawberries by soil biosolarisation

Strawberry is delicious and a high-value crop grown worldwide. Strawberry diseases are commonly controlled by soil fumigation with toxic chemicals. Alternative control techniques are thus needed. The article by Domínguez et al. presents a new technique, named biosolarisation, that combine soil biofumigation and soil solarization. Soils were biofumigated with fresh chicken manure with or without Trichoderma, Brassica juncea pellets, sugar beet vinasse, or dried olive pomace. Soils were then solarised 30 days by covering with clear plastic mulch, thus allowing the sun to warm up and kill pests. Results show that strawberry yields were similar to higher than yields using classical chemical treatments. Biosolarization with fresh chicken manure is therefore a promising sustainable option for clean strawberry production.
