| Abstract | ||
| Washington Navel orange transplants were sprayed at the beginning of each three growth flushes; i.e., spring, summer and autumn with CCC (cycocyl) or PP333 (cultar) at 1000 or 2000 ppm. All tested treatments reduced number and percentage of leaf infestation by citrus leafminers (Phyllocnistis citrlla Station). The highest infestation was recorded in summer flush and reduced in in autumn and spring flushes. PP333 cultar at 1000 ppm increased leaf pigments content compared with untreated control, while the higher level (2000 ppm) increased the percentages of foliar contents of N, K, Ca and Mg. In addition, the healthy leaves always had higher contents from carbohydrates, pigments, as well as N, P, Ca and Mg than infected ones. | ||
