facilities have been added. The cooperating stand owners have confirmed and 

 re-confirmed the basic principles of program operation. Some of the Approved 

 Farm Stand members have stated that the program is worthwhile just from the 

 standpoint of the voluntary inspection of apple packs displayed for sale and 

 for compliance to the other program requirements.'

CHEMICAL CONTROL OF WEEDS IN FRUIT PLANTINGS 



Chemicals are becoming an increasingly useful tool in controlling weeds. 

 This is true in fruit plants as well as elsewhere. Although the point has not 

 been reached where entire reliance can be placed on chemicals, they can be a 

 great help if properly used . 



Proper use involves not only application in such a way as to give good weed 

 control without injury to the crop but also in such a manner that the public is 

 protected against undesirable residues. Chemical companies have spent vast sums 

 to obtain information which will protect both the grower and the public. This 

 information has been digested, condensed, and placed on the label of every 

 package of herbicide as well as on other pesticides. Read it . Follow its 

 instructions . 



Strawberries 



Sesone is the best of available materials for weed control during the summer. 

 Since it kills weeds only when the seeds are germinating and must be changed by 

 soil bacteria to its active form, it is most effective when applied to moist, 

 weed- free soil. Retreatment in 3 - 4 weeks is usually necessary. 



The usefulness of 2,4-D in the strawberry field is strictly limited. It 

 can cause severe injury when runner or fruit buds are forming or when blossoms 

 or fruit are on the plants. Therefore, little time is left when 2,4-D can be 

 used safely. The best and safest use is in connection with bed renovation, right 

 after the crop is off and fruit buds have not yet started to form. At 1/2 - 1 

 pound per acre it can aid in controlling broad- leaved weeds. 



Some weeds, particularly chickweed, make a very rapid growth in the fall. 

 If these are not controlled at that time, they may choke out the strawberries in 

 the spring. The most effective material for this purpose is chloro-IPC (or CIPC) . 

 Severe injury to the strawberries can result from applying too much. One pound 

 per acre of ground actually covered is enough, applied after the plants are 

 dormant . 



Blueberries 



One application of diuron in early spring while the plants are still dor- 

 mant will control most weeds except deep rooted perennials, for most of the 

 summer.
