“…Fruit samples were analysed for residues 29 days, 15 days, 8 days before, as well as at harvest, by using the same methods. Details of analytical techniques are discussed by Krause, Loubser & De Beer (1986). Musts from treated and untreated vines were also subjected to standard V 0 R I fermentation tests in order to determine possible effects of nematicide residues.…”

Grapevine root growth was measured for vertical and horizontal distribution as well as seasonal growth periods. The persistance of aldicarb and fenamiphos in the soil as well as in leaves and fruit of grapevines was monitored over a prolonged period to establish behaviour patterns which inflnence chemical control strategies. Most roots occurred within 600 mm from the trunk, both vertically and horizontally. Two periods of root development occurred annually. Accordingly applications of nematicides should be made in a band covering 600 mm on both sides of the vine trunk, either after harvest and/or during budburst. Results on residues of aldicarb and fenamiphos stress the importance of adequate water supply after application. Both nematicides will reach the bulk of the roots if correctly placed and were still detected after 42 days and 70 days respectively. Applications during spring with aldicarb and fenamiphos at the dosages used will have no effect on the fermentation of grape musts nor result in toxic residues exceeding 0,05 mg/kg in the grapes.

“…200 mm strip application. *For more detailed information on these aspects see Krause et al (1986). cause of the lower solubility of fenamiphos (Hafez, Raski & Lear, 1981) more rain or irrigation following treatment would also have resulted in higher concentrations at deeper levels during earlier stages.…”

“…A sample of 100 gm of soil was shaked for one hour with 200 ml of acetonewater (3:1 v/v) according to the method of Krause et al, (1986). The extract was measured after decantation in a cylinder through a clean pad of cotton and concentrated to remove acetone and then re-extracted with 100ml methylene chloride for three times.…”

The present study was conducted to follow up the residues of one example of an organophosphate nematicide recommended for controlling nematodes and soil insects namely cadusafos (rugby 10%G). The experiment was done in banana orchard to study the persistence of cadusafos in sandy loam soil and banana fruits. The effect of hydrogen ion concentration, thermal and photolytic conditions on the persistence of cadusafos was studied. It was found that the initial deposit of cadusafos in the soil was 66.49 ppm and the half-life period was 10.83 days. The results confirmed that the banana fruits can be used safely at any time after the application of the recommended dose of rugby 10% G. The higher stability of cadusafos was found under the two chosen temperatures (30 and 40 0 C). The half-life periods of cadusafos were 8.45 and 5.33 days under the conditions of UV-rays and sunlight, respectively. The alkaline medium showed a great effect on the persistence of cadusafos especially at higher temperature. In contrary, the neutral medium (pH 7) was less effective on the persistence of cadusafos.

An experiment was conducted to evaluate the effects of some technological processes on the residual levels of profenofos, imidacloprid and penconazole in tomato fruits and products. According to their half-life (t (1/2)) values, tomato fruits can be safely harvested for human consumption or for processing purposes 3 days after the spray time of imidacloprid and penconazole and 7 days after in the case of profenofos. Pesticide residues were greatly decreased in tomato juice under cold or hot break compared with that taken from unwashed tomato fruits. A sharp decline in profenofos level was noted after treatment by pectinex ultra SP-L and benzyme M during tomato crushing.
