Show HESSIAN FLY INJURES WHEAT Pestiferous Little Insects Burrow Into In-to Straw, Weakening It and Causing Caus-ing It to Fall Over. In roily to n n"y " moihoil of rlduliiK k field Infi'stt-d with th Injurious littln Hessian fly the Wallaces' FurmiT inakf the following fol-lowing reply: The HtNsian fly nevercly danuiRcd much winter wheat lut lust fall, but the pest la not yet done with Its evil work. These browu objects which our correspondent wrongfully calls ikks will turn into little black I! lea about one Unth of an Inch lonu, re-ncnibllng re-ncnibllng hinull inoHiiultof . They will lay more eg on the wheat, and the liiugRiits which come out of thcue euK-s will, by burrowing Into the utraw, cause further damage. They wiakcn tho straw and ciiuhu It to fall over. What can we do with a field Infested In-fested with Hessian fly? If the Infestation Infes-tation is Blight, und but few of the plants are killed, we would let the ground Ktay In wheat, trusting that the wheal will stool out sullliii ntly Hessian Fly (Much Enlarged.) to make a good stand, nnd that the weather and parasitic enemies will rehire the number of fliei und maggots mag-gots of tho next brood. If the damage dam-age Is heavy, however, and practically practical-ly all the plants ure Infested and half or two-thirds of them are killed, we would probably plow up the crop and plant to oats or any crop other than wheat. Dry weather la unfavorable to the development of the little brown objects called flaxseeds, which later d'"velop Into flies. It may bn, therefore. there-fore. If the spring continues dry, there will not be much harm from the spring brood 'oi maggots. In ntost cases of very heavy infestation of wheat by the fly, and where it is desired to get the ground down to Hover, we would be inclined to disk nt the earlhst possible pos-sible moment, and reed to oats and clover. If our correspondent seeds to wheat again In the fall he would very likely be troubled ugaln with Hessian fly un-Ickh un-Ickh he plowed the stubble under or burned It off Immediately after taking oft tho present wheat crop. Kvn then he might bo troubled with flies coming In from adjaci nt fields. To prevent Hessian fly damage, rotate crops. Hessian fly docs not hurt any small grain to any extent exci pt wheat. I-iite fall seeding also helps to prevent Injury. |
