SPRAYS AND OTHER MEANS OF CONTROL 1881 



NOTES. 



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

 bodies, limbs or roots before the blossoming season opens. If blight appears during the 

 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 o rchard fruit diseases and the one most to be guarded against. 



Out out and burn all infested canes. 



Soak three hours, l^ever use treated potatoes for food. ;; 



Soak the potatoes before cutting for two hours. I>o not plant potatoes in ground from which 



scabby potatoes have been dug. Rotate with other crops. 



Sprinkle the 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, 

 one 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 gQt 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 them 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 efFectlve. 



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 ; % pint carbolic acid ; 

 IV2 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 cf 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 groun d. ___^ 



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 Sulphur 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 potatoes 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 rubbed on trunks will also act as a repellent. Otwell Tree Paint is a good repellent. 



Rabbits and ground squirrels may be 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 he trapped 



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

 roosts may 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 wood ashes. 



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

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

 possible, fumigation is best. Use cyanide of potassium (98 per cent), one ounce, by 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 deadly poison if inTwXed. and qreat care sJiotild le eis~ 

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

 gating greenhouses, it is sufficient for 350 cubic feet. 



Plow up infected 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 be rejected. This disease is 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.
