The Gray Field-Slug (Limax agrestis) of Europe has finally become 

 established in Michigan. It is a snail, less than % of an inches long, with- 

 out a shell, and it flourishes in moist places, feeding mostly at night 

 on lettuce, celery, potatoes (the tubers) and other vegetables. Poisoned 

 bran is the best we can do for it at this time. Scatter the bait in vicinity 

 of plants to be protected. (The Giant Slug is also present in Michigan, 

 but has not become widespread as yet.) 



GENERAL TREATMENT FOR TOMATOES. 



Leaf Blight. This disease can be prevented by the proper use of Bor- 

 deaux. The standard 4-4-50 formula is the strength most commonly used. 

 The first application should be made while the plants are in the seedbed 

 or coldframe. The second spraying should be made soon after the plants 

 are set in the field. This should be followed by additional sprayings 

 every ten days or two weeks until the fruit begins to ripen. During wet 

 seasons more and later sprayings are necessary than when the weather 

 is comparatively dry. 



Flea-Beetles. Small, black flea-beetles sometimes appear and eat pits 

 in the foliage of the tomato plant. The easiest way to control them is to 

 spray with Bordeaux-mixture and arsenate of lead in the ordinary way. 

 Such sprays, of course, must not be continued after the fruit begins to 

 get very large. 



Tomato Worms. The large green "worms" that devour the leaves of 

 the tomato plants can be controlled when the worms are small by a 

 spray of arsenate of lead applied in the ordinary way. 



GENERAL TREATMENT FOR MUSKMELONS AND CUCUMBERS. 



Several insects interfere with the welfare of cucumber and melon 

 vines. The Cucumber-Beetle (striped) feeds on the leaves, and the 

 young tunnel as grubs in the roots. Plant more seeds than are needed 

 to produce vines and thin out the injured plants and dust with hydrated 

 lime and flour of sulphur (one of sulphur to five or six of lime), through 

 coarse cloth. Some prefer arsenate of lead powder mixed with nine parts 

 of hydrated lime. About the bases of the vines on the ground throw 

 some tobacco dust to prevent beetles from laying eggs on stems. Paris- 

 green is not reliable on these tender vines. 



The Cucumber-Louse usually starts in a few hills and then spreads 

 over the field, cold, wet weather being favorable to the louse. Some prefer 

 to bury the first few vines attacked to retard spreading. A good spray 

 is Persian insect powder, 1/2 ounce to a gallon of water; also nicotine- 

 sulphate, 1/2 pint to 50 gallons of water, if 40% sulphate is used, spraying 

 upward from beneath. The difficulty lies in getting the spray on to the 

 lice. Each louse must be fairly hit to be killed. 



The Large Black Squash-Bug, or stink-bug, not only feeds on vines, 

 but probably also carries the wilt. It may be trapped on cold nights 

 under pieces of board and dropped into a can of water, having a little 

 kerosene on top.
