Tells How to Fight
 The Army Worm
Disappearance of Pest in Some Places Only Temp0rary-Best Methods
 To Destroy Them.

(By Geo. G. Becker, Acting Ento-
 mologist.)
 Al, houeh the fa.i army worm has temporarily abandoned the corn and cotton fields this does not mean that there Will be no more trouble from t.ls source for the rest of the year Tie worms have gone into the ground 70 change the pupae only to emerge later as moths and deposit eggs for another brood. The planters should therefore. be on the lookout for the next brood
 Right now before the moths emerge it would he we'll to blow under all lands where the damage is so great that it is impossible to make crop. The same applies to any sort of grass lands where the worms have been breeding in abundance. By this prac- tice the pupae will be buried so deep that the moths will not be able to emerge.
 Such lands may then be seeded 70 a crop which is not generally attack ed by the worm. Cow peas would make an excellent crop. Under no condition should millet or any other crop of the grass family be sowed on infested lands for they will be open to severe infestation with this worm In addition 10 blowing under these infested lands the planter should keep i up intensive cultivation with such crops as corn and cotton as long as it is possible to do so. The object of this cultivation is to keep down grass and at inc same time kill many of the tender pupae in the soil. The importance of cultivation cannot be too strongly emphasized. A recent trip over the state showed that the 1 greaest number of severe infesta- tions were due to lack of cultivation. This is because volunteer grass grew up in the fields and attracted the in- sects.
 In connection with such crops as cotton, arsenate of lead powder should be dusted on the planS. It should be applies undiluted at the rate of five pounds to the acre. Where it is impossible to get arsenate of lead powder paris green may be used by mixing with every pound one pound of lime and pound of flour. The object of the lime is to correct the burning proper v of the paris green flour is added to make it stick and not to correct the burning property. This mixture may be applied five pounds to the acre.
 Planters should neve use paris green where it is possible to get ar senate of lead powder since the for mer often causes serious burning of he foliage. Where the planters can- not get arsenate of lead of their deal CTS, they should get together now and order some of any of the leading man. utacturers so as to have it on hand when tn eoCcason demands. A list of manufacturers will be supplied up- on application to this office.
 In applying arsenicals care should be Iaken to dust the poison so that 1t will get in on the stalk and branch es since it is these parts which are usually attacked by the worms.
 Everything should be in readiness should the next brood of worms prove serious. In addition to the above sug- gestions fields should be protec. led from marching armies by making a trench around them with a blow The trenches should be plowed with the vertical side against the field so |AAe' ie VIII bC uiiilSult lOl uc WOIlllS to get out of the trenches onto the field to be protected. When worms accumulate in these trenches they may be killed by one of number of ways. Spraying coal oil on them is effective. Another method consists of sprinkling straw with coal oil scattering this in the trenches and setting fire to it.
 Where there is a strip of grass on !. the edge of he field it is good practice to poison it we'll with. paris green or arsenate of lead in order to further kill off an invading army Be Prepared for Next Year. Although the worm is not likely to appear again next year the planters should do all in their power to kill them off. This fall or early next spring all lands which were infested should be thoroughly piowed so as to bury the pupae which may be win tering over Infested grass lands which are dry enough should be burn, ed over before being plowed In as much as grasses are most affected by the worms it is not advisable to plant any cereal next year on lands which were heavily infested jhis season.
