American Gooseberry Mildew. [march, 



The Report (Part II.) of the Intelligence Division of the 

 Board of Agriculture and Fisheries for 1909-10 [Cd. 5470. 



Price is. $d.], deals chiefly with the 

 American administration by the Intelligence 



Gooseberry Mildew Branch of the Destructive Insects and 



and other p es ts Acts. 



Destructive Pests. Qnly Qne disease> American Q 00se _ 



berry Mildew, was dealt with on admin- 

 istrative lines, and an account is given of the steps taken 

 during the year, the prevalence of the disease in various 

 districts, the sources of infection, remedies, &c. 



As regards this disease, the following conclusions are given 

 as the result of the experience of the year 1909-10. 



1. American Gooseberry Mildew is wide-spread and deep- 

 seated in certain counties in England, where gooseberry 

 growing is practised on a commercial scale. There are, 

 however, many gardens even in these areas which are un- 

 affected, and many more which are only very slightly or 

 slightly diseased. 



2. Beyond these areas the disease has spread very little, 

 and where it has appeared it is found chiefly in market 

 gardens and only rarely in private gardens. 



3. The conditions under which the disease spreads or 

 becomes intense have not yet been fully ascertained. 



4. Under certain climatic conditions, such as dry or cold 

 weather, the disease does not spread with great rapidity and 

 may even tend to disappear. 



5. No sprays, hitherto tested, will destroy the disease or 

 keep bushes free from attack. 



6. The removal of all visibly diseased wood in the early 

 autumn, as soon as the wood has ripened, reduces the amount 

 of disease the following season, and will in most cases save 

 the fruit, while the neglect to prune early will not only cause 

 the bushes to become infected early the following season, but 

 may even lead to a subsequent state of infection which may 

 require some years of treatment to overcome. 



7. The removal of infected bushes to other gardens is a 

 fruitful source of infection if the plants are not properly 

 pruned. 



Under the Destructive Insects and Pests Order of 1910 

 various pests are scheduled, but no action under this Order
