BETTER FRUIT 



February, 1921 



Extent of Apple and Pear Industry. 



In connection with the enforcement 

 of this law it is interesting to note the 

 extent of the apple and pear industry 

 as shown by an inventory taken of 

 the fruit situation hy inspectors in 

 1920. From a card index record of all 

 orchards in the state there are 26,759 

 acres devoted to apples and 284 acres 

 in pears. This represents the commer- 

 cial acreage that must be sprayed for 

 codling moth as well as isolated pear 

 and apple trees throughout the state. 



In 1919 as estimated by the Federal 

 Bureau of Crop Estimates, Bureau of 

 Markets, State Department of Agricul- 

 ture, State Horticultural Society and rail- 

 road officials, the apple crop amounted 

 to 4,000 cars divided into districts as 

 follows: 



Cars 



Payette- Weiser District 250 



Boise Valley District 500 



Twin Falls District 400 



Lewiston District 350 



Emmett Valley 115 



Coeur d'Alene-Moscow District 114 



Other Districts 21 



Pears 6 



For 1920 the Department of Agricul- 

 ture figures our apple crop at 4,875 cars, 

 pears 10 cars. 



Horticultural Inspection Districts. 



Until 1920 the state was divided into 

 16 districts which was based on the 

 geographical formation and the loca- 

 tion of the fruit industry in each which 

 was designed to facilitate the inspection 

 service. In 1920 the state was divided 

 into inspection districts based upon the 

 car-lot production of commercial fruit. 

 It is now divided according to the fol- 

 lowing districts with an inspector in 

 charge of each district: 



Boundary County District. 



Bonner County District. 



Kootenai County District. 



Latah County District. 



NezPerce-Lewis-Clearwater County District. 



Jonathan-Crystal District. 



Payette-Crystal District. 



Washoe Bench-Payette District. 



Fruitland District. 



Council District. 



Boise-Beatty District. 



Perkins District. 



Meridian-Eagle Heights District. 



Nampa District. 



Middleton-Homedale-Caldwell District. 



Parma-Apple Valley-Boswell District. 



New Plymouth District. 



Emmett Valley District. 



Twin Falls-Filer-Buhl District. 



Idaho Falls District. 



Blackfoot District. 



Pocatello District. 



Detailed Plans of Codling Moth Control. 



The conditions during 1919 were ex- 

 tremely favorable for the congenial de- 

 velopment for fruit pests, particularly 

 codling moth, San Jose scale and red 

 spider, and due to much lack of interest 

 on the part of many growers in caring 

 for their orchards the loss from worms 

 and scale for this year as proven by the 

 cull pile at harvest time was estimated 

 at 25 per cent average state loss of the 

 apple crop, 15 per cent being due to 

 worms and 10 per cent being due to 

 scale. By redividing the state, strength- 

 ening the inspection service under the 

 reorganized Department of Agriculture 

 and a concerted effort on the part of 

 the growers to reduce the culls due to 

 codling moth and scale to the lowest 

 possible amount in 1920 the following 

 plan was inaugurated and carried out: 



Codling Moth Control Based Upon a 



Study of Its Life History 



and Activities. 



"You have been sent 20 pieces of mos- 

 quito netting for the purpose of making 

 an inverted cone around 20 trees for the 

 purpose of trapping the emerging adult 

 codling moth. These trees should be 

 selected in various parts of your dis- 

 trict which will represent the various 

 elevations and environments which 

 you believe will influence the activity 

 of the codling moth. These cones 

 should be placed on the trees just as 

 soon as the calyx spray is given. Cut 

 out the center of the cloth to fit the 

 size of the tree trunk, tie this tightly 

 around the tree trunk with a strong 

 cord so the moth cannot escape between 

 the bark and the cloth, placing the 

 cloth about 2 feet up the trunk. Spread 



out the bottom of the cloth in a circular 

 manner as far from the tree trunk as 

 possible. Peg it down first with small 

 sticks and then cover the edges firmly 

 with dirt which will prevent the wind 

 from blowing up the edge of the cloth. 

 This will make an inverted cone. The 

 essential thing is to pick out locations 

 and trees where you have the greatest 

 chance of trapping a number of emerg- 

 ing moths. These will be coming from 

 under rough bark on the trunk and 

 rubbish on the ground near the base of 

 the tree. Watch these cones from day 

 to day for the emergence of adult moths 

 which you will see fluttering under 

 the cloth. The insect control poster 

 which you have distributed in your dis- 

 trict gives the details of how the traps 

 and burlap bands are used. 



"When the first moths appear advise 



Your 1921 



Fruit 

 Tonnage 



When planning the handling of your fruit 

 tonnage this year, we recommend that 

 you consider the merits of independent 

 marketing. 



Prior to the advent of Produce Reporter 

 Organization independent marketing was 

 fraught with grave risks, but since the advent 

 of the "Blue Book" you can ship to distant 

 points with impunity.
