Abstract: Undesired organisms, including insects, mites and fungi, may be combated by application of a liquid composition which comprises starch dextrin or an analogous derivative of amylopectin as an active ingredient. The aforementioned active ingredients may be used as the sole active ingredient or in combination with other active ingredients. Examples of undesired organisms which have been found to be affected are whiteflies, thrips, red spider mites, broadmites, cucumber powdery mildew and oat powdery mildew.
Abstract: Undesired organisms, including insects, mites and fungi, may be combated by application of a composition which comprises a carbohydrate, protein or glycoprotein, or a functionalized derivative of any of these, as an active ingredient. Examples of materials which have been found to have relevant activity are sucrose, hydroxypropyl methylcellulose, starch and dextrinised starch. Examples of undesired organisms which have been found to be affected are whiteflies, thrips, red spider mites, cucumber powdery mildew and oat powdery mildew.
