Preparations produced on the basis of lignosulphone zinc complexes for fibre flax crops (Linum usitatissimum) were studied in the conditions of the Republic of Belarus. It was determined that treatment with preparations with anticholosis (Colletotricum lini Manns et Bolley.) and fungicidal features based on lingosulphone zinc complexes made it possible to decrease flax crops resistance to anthracnose. The positive influence of preparations on flax plant growth and flax straw yield and seeds was marked. Studying of new preparations on the basis of iron and zinc chelates determined that ferro-lignosulfonate in dose of 6,0 l/ha was ineffective against calcium chlorosis. Application of lignosulphone zinc in doses of 6,0 and 10,0 l/ha lowered the extension of calcium chlorosis on 60,2% and 67,6%, respectively, as well as the pathological process - on 65,7% and 71,9%, in comparison with control. The highest efficiency against calcium chlorosis and anthracnose was stated in the conditions of flax crops treatment with zinc lignosulfonate and N addition in the form of urea in dose of 10,0 l/ha
