CHPJIICAL \TO:EDING of STRAYfBERRIES 



Grower trials of CH#1 for weeding strawberries have been very encouragirg. It 

 hasn't eliminated all weed troubles but thosswho have tried it feel that it is worth 

 trying ai:iother year. It has reduced the nujaber of hoeings necessary as well as the 

 time required for each hoeing. 



At this time of year chicloffeed is the number one problem in strawberries. If 

 it isn't controlled in the fall, it can become extremely serious in the spring. It 

 has been found that certain dinitro herbicides can clean up chickweed in good shape 

 if properly used. 



The time to use these DN sprays is after the strawberry plants become dormant 

 and before the winter mulch is applied. For rmich of the state this will be between 

 Hovember 1 and 1^, Since these DN sprays are "burning" sprays, they work better on 

 warm sunny days. Also they work better if they can be applied when the weeds are 

 small, before they get beyond the second true leaf stage. The weeds must be thorough- 

 ly wetted with the spray. Hence, the amount of spray needed per acre will depend on 

 the size of the weeds and the density of the weed population. Somewhere between 25 

 and 100 gallons per acre v^ill usually do the job. If tlie DN is water soluble, one 

 pound of actual DN per acre is sufficient. If it is oil soluble, use one quart of 

 1% material plus fifteen gallons of kerosene and sufficient water to make 100 

 gallons of spray. These sprays will burn the strawberry leaves as well as the weeds 

 but after the plants have become dormant this will do little if any damage. Do not 

 use more than one application. 



The DN's to use are DNOSBP or DNOSAP or their salts. For brand names consult 

 your county agent,

TOBY'S TRAVELS 



Having been granted a leave of absence for five months to enable me to study 

 the fruit industry°of the United States by visiting fruit producing areas and 

 experiment stations, the Editor of FRUIT NOTES suggested that^I write a series of 

 articles describing some of my experiences along the way. This is the first 

 contribution. 



Mrs. Roberts and I left Amherst August 31, and, after spending a week with our 

 son and family in Connecticut, travelled through the picturesque Catskill mountains 

 to Ithaca, New York to attend the meeting of the American Society for Horticultural 

 Science. The sessions of this meeting consisted chiefly of a series of scientific 

 papers on various horticultural subjects presented by experiment station workers from 

 all parts of the United States. 



Since, in the field of Pomology alone, papers were being presented simultan- 

 eously on different subjects in different rooms, one had to choose which session he 

 would attend. I chose to attend the session dealing with post-harvest physiology or 

 the handling of fruit after it is harvested. Many of these papers dealt with new 

 developments in the use of controlled atmosphere storage and air conditioning by the 

 use of activated coconut shell carbon. There seemed to be no argument among the 

 scientists but that these were effective means of delaying ripening. However, some 

 questions as to vrfiy these methods are effective have not been ansvrered. The ultimate 

 result of this research will be to enable growers and handlers to get fruit to 

 consumers in better ccnditdcn than ever before and thereby increase demand.
