the summer spores of mildew do not live long, and every day's 

 delay in bringing baskets near gooseberry bushes makes the risk of 

 infection less. 



3) Labourers who have been working in a garden in which the 

 disease exists in its summer stage should not be set to work in a 

 clean gooseberry plantation for a week at least unless means have 

 been taken to disinfect their clothing. 



4) Growers should make a practice of searching their plantations 

 for traces of disease at frequent intervals, especially in the months 

 of July, August, and September. Young leaves which are attacked 

 generally curl upwards and show a white under surface covered 

 with mildew. Pickers should be told to report at once any cases 

 of mould on the berries. As indicated above, outbreaks of disease- 

 in plantations in which mildew has not previously appeared are very 

 often found near packing-sheds, so that special care should be taken 

 in examining bushes near the places where gooseberries, plums, etc. 

 have been got ready for market. 



5) As disease may appear at any time between May and No- 

 vember, fruit-growers should keep on their premises a few pounds 

 of liver of sulphur. This substance, when freshly made up, as 

 explained below, is the best spraying material for summer use. 

 A good quality should be procurable at 6d. per Ib. It must be 

 kept in an air-tight tin or a corked bottle, for if exposed to air 

 it quickly loses its value. A spraying pump should also be kept 

 in readiness. The ordinary knapsack sprayer costing about 355. 

 would serve for ordinary plantations, or a hand-pump of the syringe 

 pattern costing 75. 6d. to 155. might be used in small gardens. 



Treatment of a First Outbreak. Assuming that a watchful fruit- 

 grower discovers the disease as soon as it gets into his plantation, 

 he should at once remove and destroy the affected berries or 

 shoots; they may be collected in an iron bucket and burned, or 

 dipped into a "steep" made by dissolving i Ib. liver of sulphur 

 or i Ib. bluestone in 10 gallons of water. A spraying mixture 

 should then be made up of i oz. liver of sulphur to 2 gallons of 

 water, and the affected bush and surrounding bushes should be 

 throughly sprayed. 



Treatment of Diseased Plantation-^ adopting the line of treat- 

 ment indicated above, the chances of stamping out the disease are 

 good ; but if from neglect or any other cause a garden has become 

 generally infected with disease, a different procedure will be re 

 quired.
