| Abstract |
Sugar cane plants infested with common borers (Sesamia critica (Lederer) and Chilo Agamemnon (Bleszynski), meaiy bugs; Saccharococcus sacchari (Cockerll) and in recent years with soft scale insect; Pulvinaria tenuivalvata (New.). Because of some síages of these pests are present in the soil and difficulty of chemical control and their environmental problems. The effect of adding solar with irrigation water on controlling sugarcane insect pests and its effects on soil microorganisms, soil enzymes and some main soil properties were measured. This study carried out in Edfu, Aswan Governorate throughout 2003- 2004 and 2004-2005 seasons. In the first season Solar was used at rate of 30 Liters /fed as compared with untreated control. In the second season one plot irrigated with 30 liters solar, the second irrigated with the same dose but two times and the third plot was irrigated without solar. The data indicates that solar application significantly affect the infestation of soft scale insect in both seasons, whereas the number of insects (nymphs & adults)/leaf in the first growing season were 59.1 and 21.8 in control and treatment respectively. These numbers were 40.23, 10.31 and 5.31 insects/leaf for control, one time and two time addition respectively. It has significantly effect on mealy bug in the first season, while in íhe second season it was signifícantly. The number of Gird Led plants caused by C. agamemnon was signifícantly higher in control plot than in treated plots with average of 4.67 and 1.0/20 plants in control and treated plots in the first growing season and 2.67, 1.67 and 1.0/20 plants for control, or.e time and two time addition respectively. Solar addition showed no marked effect on soil salinity either in one or in two time addition. Major changes in saturation percentage (SP) due to solar addition were not detected and soluble anions were free of carbonates. Results indicate that solar treatment could be recommended for controlling sugarcane pests and it hasn't any harm effect on microorganisms activity. Using higher amount of organic matter and biofertilizers with efficient microorganisms to avoid decreasing counts with solar addition is very important.
