240 g l -1 , 96.0 g AI ha -1 . Abamectin 18 g l -1 , 18.0 g AI ha -1 and Abamectin 18<br />
g l -1 , 9.0 g AI ha -1 gave statistically lower toxicity to strawberry mite in comparison<br />
with Abamectin 18 g l -1 , 21.6 g AI ha -1 and Sp<strong>ir</strong>odiclofen 240 g l -1 , 96.0 g AI ha -1 in<br />
2005 (Table 4). The toxicity of Lambdacihalotrin 50 g l -1 , <strong>25</strong>.0 g AI ha -1 was similar<br />
to the lowest rate 9.0 g AI ha -1 of Abamectin 18 g l -1 in 2005 (Table 5).<br />
