Until the season of 1920 the Mississippi Station had made no 

 attempt to control tlie cotton boll weevil [Anthonomus grandis] with 

 poisons, but in that year the damage was so great that some growers 

 ploughed up their cotton and planted the land with other crops. 

 On the station farm, in spite of several hand-pickings, many of the 

 cotton stalks had every square punctured. Hand dusting was 

 then begun with calcium arsenate, three applications being given at 

 intervals of about six days. After this treatment the percentage of 

 infestation was so low that poisoning was stopped for a time and begun 

 again in late July, but it is uncertain whether the good results were due 

 to poisoning or to the frequent rains that began about the same time.

By the regulations of March 1920 the importation into Mississippi 

 is forbidden of all cotton lint, cotton seed, etc., and all things or 

 materials used in connection with growing, harvesting, baling or 

 manufacturing cotton lint or cotton seed, from foreign countries, the 

 States of Louisiana and Texas, and from all States in which the 

 pink bollworm, Platyedra (Pectinophora) gossypiclla, may hereafter 

 be found to exist, and from all States other than Louisiana and 

 Texas unless accompanied by a special permit from the chief inspector 

 of the State Plant Board of Mississippi giving evidence regarding the 

 point of origin of the material and any other information necessary 

 to establish the safety of such consignment or its freedom from 

 possible infestation by P. gossypiella. 



These regulations are modified under date 1st September 1920 to 

 refer only to known infested and regulated areas, and certain exceptions 

 to the prohibition order are enumerated.

In view of the increasing loss caused by pests and diseases to 

 stock-raising, forestry and agriculture, a decree has been passed 

 by the Mexican Government rendering it obligatory on the part of 

 agriculturists and stock-raisers to notify the Secretary of Agriculture

 measures may be undertaken. These will be prescribed by the Depart- 

 ment of Agriculture, and must be carried out within a given limit of time,
