| 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, whitefly, Bemisiatabaci (Genn.)(Homoptera: Aleyrodidae). This work was aimed tostudy effectiveness of acetamprid alone and binary mixtures with oil and foliar fertilizer against whitefly larvae mortality, egg hatchability (under laboratory condition) and yield of tomato plants.The results showed that in case of egg hatchability, adding fertilizer to oil, fertilizer to acetamprid and oil to acetamiprid cause decreased in hatchability percentage compared with other treatments. Also, the results illustrated that adding of fertilizer to acetamiprid or oil causing increasing in reduction percentage to B. tabaci larvae.In case of initial effect when adding fertilizer to acetamiprid cause increasing mean reduction percentage to 92.61% recording the first superior treatment. The results showed that adding foliar fertilizer to oil or acetamprid and oil toacetamprid recorded 85.48, 83.12 and 77.95% reduction, respectively. In case of tomato yield during two summer successive seasons 2016 and 2017, the results reported that the tomato yield increased when adding oil to acetamprid recorded 609.45 Kg during 2016 season with increasing value of 40.17% compared with control and other treatments, but control record the lowest yield (433.09 kg). During 2017 summer season, adding oil to acetamiprid recorded superior yield of 621.53 kg with increasing 35.53% compared with control. Impact of adding oil and fertilizer on residues of acetampridon tomato fruits (washed and unwashed): Unwashed fruits in case of acetamiprid alone recorded residues up to maximum residue limit until 12 days from spray but addition fertilizer or oil to acetamiprid cause disappearance acetamiprid in 9th day from spray. Wash using water or acetic acid caused speed disappearance toacetamprid. | ||||
