SPRAYS AND OTHER MEANS OF CONTROL 18S1 



NOTES. 



There is no spray remedy for this bacterial disease. Carefully remove all infections in the 

 bi dies, limbs or roots before the blossoming season opens. If blight appears during tlie 

 growing season, remove it, using great care to cut well below infection point. Wipe the 

 instruments and cuts with corrosive sublimate (bichlorid of mercury) 1 to 1000. This is the 

 most serious of all orchard fruit disea ses and the one most to be guarded against. 



Cut out and burn all infested canes. 



Soak three hours. Jscvcr use tnaied potatoes for food. 



Soak the potatoes before cutting fi r two hours. Uo not plant potatoes in ground from which 

 scabby potatoes have been dug. Rotate with other crops. 



Sprinkle tlie grain thoroughly, mix on a bin floor, let dry and sow. 



Mix well. Dust the plants well before worms eat in. If plants are heading, use white hellebore, 



cne ounce to two gallons of wate r. 



Make a mash by adding some water; add a little molasses and salt; mix and scatter in small 



piles among plants or in bed before planting. Be careful that chickens do not get at the 



poison. Black-leaf 40 (1 to 800) may also be used to saturate the ground. 



Poisoned slices of potatoes may or may not be readily eaten. The use of black-leaf 40 (1 to 



800 ) applied to the ground about the plants will drive tbem away. See formulae. 



Dust the sulphur on the vines frequently during the summer. If applied while dew is on the 



vines, it will adhere much better. Atomic Sulphur spray more effective. 



Band the trees with "Tree Tangle-foot." Tar or other sticky preparations should not be applied 



directly to the bark of trees. 



Wrap young trees with heavy building paper at least a foot above ground, and have wrapper 



extend two or three inches below surface. Young pear trees are not troubled so seriously. 



It is also a good plan to shade the trees by driving a shake into the ground on southwest 



side. Place shake three to four inches from tree. Inter-cropping with corn also effective. 



Use wash made as follows; 5 gallons whitewash; 1 pint liquid glue; Vq pint carbolic acid; 

 IV, ounces Paris green. Apply about May 1st. This remedy is not entirely effective, and 

 trees should be examined for borers. Another treatment is to apply two coats tf warm 

 asphaltum with brush in spring to trees after borers have been dug out. The asphaltum 

 coat may reach five inches below to five inches above the ground. 



Three weeks after cutting stops, spray with whale oil soap and water (6 pounds soap to 50 

 gallons of water), then dust with flowers of sulphur at the rate of 100 to 150 pounds per 

 acre. A month later, apply on dewy mornings, 150 to 200 pounds of flowers of sulphur per 

 acre. Atomic Sulphu r spray more effectiv e. 



There is no known remedy. Destroy infested plants before May 1st. Do not replant in 

 infested ground. 



Do not plant in soils in which diseased plants have grown. Practice rotation with other crops. 

 Use corn, small grains for at least two years, then plant only carefully selected clean seed. 



Mix well together and leave where ants can feed upon it. The ants will go to their nests after 

 eating and will die. Species which are cannibalistic will be killed upon eating the poisoned 

 ones which return to the nests. 



Cut p< tatoes or carrots in two lengthwise. Spread arsenic on cut surface and pin the parts 

 together with toothpicks or sharpened matches. Put poisoned vegetable in ground where 

 gophers are working. 



Liver ru bb ed on tru nk s will also act as a repellent. Otwell Tree Paint is a good repellent. 



Rabbits and ground squirrels may he poisoned with strychnia sulphate. This poison may be 

 applied directly to apples where they will be eaten. There are also proprietary poisons pur- 

 chasable at drug stores. Moles must be trapped 



Poultry houses should be thoroughly sprayed with a strong lime-sulphur solution, while the 

 roosts ma.v be washed with carbolic acid solution (six ounces of crude carbolic acid to one 

 gallon of hot water). Dust baths may be of fine road dust, equal parts of sulphur and pow- 

 dered tobacco or wr'od ashes. 



Walls and furniture may be sprayed with 1 to 500 solution of corrosive sublimate in alcohol. 

 Alcohol win dissolve paint or varnish on wood .Tnd water may be used instead. Where it is 

 P'^ssible. fumigation is best. T'se cyanide of pot.nssium (08 per cent), one ounce, hy weight; 

 sulphuric acid (crude), one ounce, liquid measure; water, two ounces. Place water' in earth- 

 enware dish; add the sulphuric acid and then drop the cyanide of potassium in. Get out of 

 the room quickly, and close doors and windows tightly. Do not enter until room has been 

 thoroughly ventilated. This is a most ilrndlti poison if inhaled, and qrcat care should be ex- 

 ercised in its use. The above formula is sufficient for 100 cubic feet of space. For fumi- 

 gating greenhouses. It is sufficient for .^no cubic feet. 



Plow up infec ted fields and rotate in grain for at least two years. ~ 



This Is a bacterial disease of a large number of species of plants of widely separated genera. 

 There is no cure or remedy. All plants, such as pears, apples, peaches, etc., found to be 

 infected should he rejected. This disease la more serious In our dry regions. 



Place In shallow dishes in the bins. The gas, being heavy, will go downward. Or use potas- 

 sium cyanide as above. 



See formula e. 



This spray destroys mustards, dandelion, thistles, ragweed, and other broad-leaved plants.
