Show TELLS HOW TO FIGHT ARMY CUT li'O.HI PEST In a bulletin lasuod by Dr. I. D. Ball, director of th experiment station at Loaaa. the action of th army cut worm. an alfalfa pest, are dascrlbad and In-atructiona In-atructiona ar given aa to bow beat to fight th post. Th army cut worm gets '- tiTm- i I Xastthal.aiany pf the Insects travel togetber and in th earns direction la search of food. ' In telling of the beat methods for fighting fight-ing th worm. Dr. Ball lays: "It la difficult to destroy this pest wnen It once gets Into a growing crop. A migrating awarra of them can - be topped by a ditch full of water, bit which they will fall and pile up. From thla ditch they can be shoveled and burled. The water doea aot kill them and If they dry our once ar aa good aa ever. If water la aot available, a trench a root In depth with th aid towarda which they ar traveling mede perplndlcular or allghtly overhanalns will serve to atop them and by digging pita along the trench they will fall Into these and can be burled. On grain flelda where the grain la email a large number caa b killed during the warmer part of tha day by running a roller over them. In alfalfa flelda there la llttl possibility ot deatmylng them until the alfalfa I cut. By cutting th alfalfa and getting It off thoae that remain can be destroyed by dragging with a brush drag which Is heavily loaded with rocks. This will crush them Into the, ground and destroy moot of them. "It hsa almost Invariably happened that where they become ao numerous aa they are this yssr thst their psrasltes In-rreass In-rreass so rapidly that the latter usually destroy the peet so thst scarcely a aln-gle aln-gle worm ia left to reappear again next season. In the Case of tha Tooele outbreak out-break there were none seen after they went Into th ground. "It la very probable that the ' paraattea will be able to handle thla outbreak. By examining th esterplllara a little later to the aeaaon we will probably be able to predict In advaaoa whether thla will happen hap-pen or not. "In rase these worms get Into young orchards, garden patches or olaces of Ilk nature. It mav be possible to destroy de-stroy them by mixing bran or aborts, fifteen pounds to on nound of whits srsenle and two oounda of suaar. By lust allghtly dsmnenlna this mixture the sugar will cause ths srsenle to stick to the bran and th mixture can then he sown broadcast In Pisces where stock or chickens can aot get it and th aroma deatroyed. Another method Is to tske clover or young alfalfa and din It Into a mixture of lead srssnste and water, about five pnunda of tha poison to twenty gallons of water, and then aprlnkle thla over the place where . tha worms are thickest." |
