fects, if any, repeated applications of the herbicide dichlobenil 

 (Casoron*) have on fruit trees. In order to eliminate as many var- 

 iables as possible paraquat, a chemical mower, is being used to sup- 

 press weed and grass growth under untreated check trees and under 

 treated trees as well. Two applications, the first in mid-May and 

 a second in late June, are necessary to suppress growth for the 

 season . 



In 1968, the second application was made on June 25, a cloudy 

 day with the threat of rain. Paraquat was applied at the rate of 

 2 quarts per acre plus 8 ounces of spreader. It began to rain in- 

 termittently while the first trees were being treated. When three- 

 quarters of the trees had been treated, it began to rain steadily 

 and the remaining trees were treated in the rain. Intermittent 

 rain continued for the next 3 days. 



On July 2, the orchard was visited to see if it was necessary 

 to apply paraquat again. Surprisingly, in spite of heavy rains, 

 the paraquat had done its job and it was not necessary to repeat 

 the treatment. - Dominic A. Marini, Regional Specialist, Southeast

The study showed that apple production increased in the Uni- 

 ted States during the 16-year period from 1951-1966 at an average 

 rate of 2.3 million bushels per year. Although year-to-year vari- 

 ation in production occurred throughout this period, fluctuation 

 has become much milder since 1951. This would indicate the use of 

 improved cropping systems during this period. 



Use of apples for processing has increased both in actual ton- 

 nage and in percentage of the total apple crop. In 1947-1950, 

 26.8% of the total crop was processed whereas the percentage in- 

 creased to 41.7% during 1963-1966. On the other hand, the per cap- 

 ita sales of apples for fresh use decreased during 1947-1966, but 

 due to the population increase total fresh sales remained approxi- 

 mately constant.
