bush and surrounding bushes should be thoroughly sprayed. 

 Those who do not possess a spraying pump may use an 

 ordinary syringe or a watering-can. After the spray has 

 dried, the affected bushes should be dug up and burned, or 

 the young wood should be removed. If many twigs or 

 berries are covered with mildew when the disease is first 

 observed, the bush should be sprayed before any attempt is 

 made to remove the diseased material. 



In treating American Gooseberry Mildew, the first essential 

 for success is prompt action. Since the spread of the infec- 

 tion may be very rapid, it is recommended that where very 

 little mildew is to be seen, it should be cut off and destroyed 

 immediately. The shoots removed must not be carried 

 through the plantation. They may be destroyed as indicated 

 above, or buried below the bush from which they have been 

 taken, and covered with several inches of soil; only twigs 

 affected by the white stage should be thus covered up : the 

 brown stage of the fungus must always be destroyed by 

 burning, never buried in the soil. When many twigs have 

 become diseased there is much danger of spreading the 

 mildew while working among the bushes, and the bushes 

 should therefore first be sprayed. The spray will destroy 

 much of the mildew, and the risk run by working among 

 the bushes will be greatly reduced. 



On any bush upon which mildew has been seen, and also 

 on the bushes in contact with the diseased plant, there will 

 probably be a number of recently infected twigs, which will 

 bear no visible traces of disease. Thorough spraying will 

 do much good, but as it is very difficult to ensure that the 

 spray wets every part of a bush, the safest plan is to remove 

 and burn the infected and suspected bushes as soon as 

 possible after the mildewed twigs have been destroyed as 

 recommended above. If this is not done, the bushes must 

 at least be very carefully pruned so as to remove all young 

 wood that may be infected. 



In the above recommendations it is assumed that spraying- 

 materials are at hand; should this not be the case, a bucket 

 containing paraffin should be procured, and all diseased 

 material should be removed, dipped in paraffin, and burned 

 at once. It is better to risk the danger of spreading infection
