| Abstract | ||||
| Tomato is the most widely grown vegetables in the world and also the most important item of the vegetables processing sector. Tomato is important vegetable plant in our agriculture map which used as food in many countries of the world and especially Egypt. It infested with many pests, among of the most serious pest, tomato leaf miner, Tutaabsoluta (Meyrick) (Lepidoptera: Gelechiidae). This study was aimed to investigateefficiency of Imidacloprid applied alone and in a binary mixture with Sylgard 309 adjuvant against this pest under field conditions, effect of Imidacloprid on tomato yield and determination of Imidacloprid residues in tomato fruits and soil. Results illustrated that adding Sylgard 309 adjuvant to Imidacloprid caused increasing mean reduction percentage to 98.02%, recording the first superior treatment. In case of tomato yield during two summer successive seasons 2014 and 2015, results reported that tomato yield increased by adding Sylgard 309 adjuvant to Imidacloprid and recorded superior yield of 600.75 and 613.15 Kg with increasing value of 41.27% and 35.44%, respectively during seasons 2014 and 2015 compared with control.Unfortunately,adding Sylgard 309 adjuvant to Imidacloprid was causation in increasing the half-life (T½) values and the quantitiesof residues in tomato fruits and soil,that were less than the maximum residue level (0.5 mg/kg). | ||||
