Use of lignosulphonates for plant protection

摘要

The present invention relates to the use of lignosulphonates in the protection of plants. The lignosulphonates have a variety of applications, such as forming a top layer on the soil in which plants are growing to inhibit emergence of weeds or reduce evaporation of water from the soil. Lignosulphonates also find application in the induction of plant defense and in the control of plant pathogenic nematodes.
