 Again a water check and unsprayed check were incorporated into the 

 test. 



A lOX Bausch & Lomb'^ hand lens fitted with a 1/8" thick plexiglass 



2 

 plate enscribed with a one cm grid divided into 25 units, replaced the 



o 



1 cm rubber stamp and hand lens method previously used (Allen, 1976). 

 One sample was taken from ten randomly selected fruit on each test tree, 

 This was repeated for each treatment and replication over a five week 

 period. 



The rating of the chemicals was determined by Duncan's new multi- 

 ple-range test. As the chemicals lost efficiency they were rated at 

 least, moderate, or best control. The labels, poor or good control, 

 were not used since no effort was made to correlate the control to 

 economic thresholds or crop production yields. 

 Results and Discussion 



1975 field acaricide spray tests . A Poisson distribution existed, 

 so transformed data were generated. Table 22 displays the average 

 transformed (Y) and untransformed (X') value for each treatment. An 

 analysis of variance (ANOVA) for significant differences between the 

 control data and the chemicals proved statistically significant. This 

 significance permitted further statistical evaluations using just the 

 toxicants. By using the chemical data and excluding the controls from 

 further ANOVA more sensitive tests were possible. The control data 

 (both water control and unsprayed control) were tested by ANOVA for 

 statistically significant differences (Table 23). No statistically 

 significant difference (SSD) was found so, for the sake of this experi-
