Enemies. Insects.—The wheat plant has many enemies to contend with in the form of insect pests, fungous diseases and weeds of many sorts. The two most injurious insect enemies are the chinch-bug and the Hessian fly (Figs. 905-907). The annual losses caused by these two pests in the wheat-fields of the United States is beyond estimate, but will run into millions of dollars. Remedies to counteract their ravages are largely preventive ; in the case of the chinch-bug, by clean tillage and rotation of crops, and of the Hessian fly by late seeding, burn- ing .stubble and otherwise hindering the propaga- tion of the brood. Other insect pests may at times cause local damage to the wheat crop, but are of less importance. Diseases.—Two rusts commonly occur on wheat, the early orange leaf-rust (Puceinia rubigo-rera) and the late stem-rust (Puceinia graminis, occurring also on oats). These rusts may also destroy the crop within a few days. Rust is now being con- trolled by growing resistant varieties. Of wheat smuts there are two: The loose smut (Ustilago tritici) matures its spores at blossoming time, the then drain and dry. Care must be taken to apply the solution to all vessels and machinery used wherever the seed might become infested by contact. Loose smut is not controlled by either of these methods.
