| Abstract | ||
| This study was conducted at the fields of College of Agriculture in Abu-Ghraib, to investigate the effect of spray of foliar fertilizer Nabata - LTB on the population density of the broad mite, Polyphagotarsonemus latus on potato plants, during the fall season of 2007-2008. Potato plants were sprayed at the age of 4-5 true leaves, followed by three successive applications of ten days interval. Results indicated that the numbers of eggs, larvae and adults were significantly different in some treated plants. The number of broad mite in 6th week of plant age was 8.66, 5.66, 9.33 eggs, larvae, adults/leaf respectively in control. Moreover, the higher density for eggs, larvae, and adults 23.00, 15.66, 19.66 eggs, larvae, and adults was in the 8th week of plant age. In the 14th week the density was reduced as the plant get 0.66, 0.66, 0.33 eggs, larvae, and adults respectively. | ||
