The text is given of an Act adopted on 22nd October 1920 to prevent

Lewis (A. C.) & Chase (W. W.). Control of CurcuUo and Brown Rot 



of Peaches. — Georgia State Bd. Ent., Atlanta, Circ. 34, February 

 1921, 4 pp. [Received 7th November 1921.] 



Heavy losses occurred to the Georgia peach industry in 1920, largely 

 owing to lack of thoroughness in spraying and other remedial measures. 

 A revised spray schedule is given, based upon experiments of the 

 last ten years [R.A.E., A, viii, 277], and further improvements on it 

 may be expected. The two chief causes of loss are the attacks of the 

 peach curculio [Conotrachelus nenuphar] and the brown rot that so 

 frequently follows its punctures. To guard against these, the trees, 

 should be pruned after the leaves have fallen, so as to allow the 

 entrance of sunshine and free circulation of air. They should then 

 be thoroughly sprayed with lime-sulphur solution. As early in 

 autumn as possible all rubbish about the orchards should be burnt, 

 by 1st November if practicable. Frequent shallow cultivation should 

 be practised under the trees during May, June and July, in order 

 to destroy the pupae' of C. nenuphar. During the summer the spray 

 schedule should be followed. Immediately after the harvest of each 

 variety, all fallen fruit and any left on the trees should be gathered 

 and destroyed ; this should be done within a week, before the larvae 

 in the fallen fruit enter the soil for pupation. This fruit should either 

 be buried under 24 inches of soil or mixed and covered with quicklime 

 and wetted, in order that the heat generated may kill the larvae.

Season. — Georgia State Bd, Ent., Atlanta, Bull. 59, February 1921, 

 16 pp. [Received 7th November 1921.] 



During 1920, experiments were undertaken to determine more 

 accurately the value of calcium arsenate [R. A.E., A, viii, 302] against 

 the cotton boll weevil [Anthonomus grandis] under Georgia conditions. 

 The results showed that this poison, properly applied, is a successful 

 remedy. In heavy infestations the dust should be applied once or
