"Alfalfa Weevil" A series of articles on the control of alfalfa weevil has been run in all local papers. Remember alfalfa weevil wee-vil is an individual problem. Alfalfa weevil can be controlled on an individual in-dividual farm. ihe last short time there seems to be a development of a lot of alfalfa weevil in Utah County. Coun-ty. The problem is to cut It in the early .stage before development of the weevil takes place as this determines, deter-mines, in a large measure, the amount of alfalfa weevil next year. WEEDS Weeds are taking many Utah county coun-ty farms. Crops are being destroyed destroy-ed and utilizing moisture intended for the crop. Preventing seeding and spreading of under-ground roots by clean cultivation. Organizations and Individuals should cooperate immediately immed-iately on weed control. Methods to Control Corn Ear Worm Severe damage is done by the corn ear worm in Utah county. Prof. J. C. Hogen.son of the U. S. A. C, states that: j The control of the corn ear worm Is a rather difficult problem because be-cause it cannot be handled by spray- ' ing with any kind of chemical poi- ' son. When its life cycle, is under;iood, however, its control becomes a rath- ' er simple, though continuous, pro- j cess. The adult of the corn ear worm ( Is a moth which lays its eggs at c random on any part of the corn' plant. One female moth lays about 1 1000 eggs during a- period of about f 12 days. 1 1 There are usually irom one to four j ' generations in a year, depending , ! upon the length of the worm season. sea-son. The eggs hatch in about eight days after they are deposited." After Af-ter hatching the worm enters the ear and grows rapidly. It is during dur-ing this stage of its development that damage to the corn is done. When fully grown the worm leaves the ear, usually by boring out through the husks, and drops to the i ground. It enters the soil and bores down to a depth Of from one to nine inches. Here pupation takes place. During this period it Is very delicate &nd helpless. When the changes have been completed, which usually take about 14 days, the full-grown moth emerges from the soil. The control of this pest lies mostly most-ly In destroying the pupae in the soil during its delicate and helpless period. Tills consists of three practices: (1) Rotation. Do not plant corn on the same ground two years in succession. suc-cession. (2) Deep weekly cultivations. cultiva-tions. (3) Deep fall plowing to destroy de-stroy the eggs of the last generation. If these three practices are used the corn ear worm can usually be kept under control. |
