The 1976 mite population was in a declining state from week 2 

 through 5. This could account for the fact that no treatment by week 

 interaction was discernable during the 1976 trials. As with the 

 earlier tests, as the population was declining, the ANOVA could not 

 detect a statistical TxW interaction. 



For the aforementioned reasons, the Duncan's new multiple-range 

 test for 1976 data was tested across the weeks instead of weekly as in 

 the 1975 evaluations. This multiple week comparison gave only an 

 overall breakdown as to the chemical's effectiveness. 



Chemical standards . Different chemical standards were used for 

 the 1975 and 1976 acaricide tests. Dicofol at .03% was used in 1975 

 and chlorobenzylate at .01% in 1976. These chemicals are recommended 

 for use on citrus in the 1977 edition of the Florida citrus spray and 

 dust schedule.
