Refined oils of the Stoddard solvent type, safe and effective for handling carrot crops, were developed after a relatively short period of research. Their use spread to celery, parsnips, parsley, and anise. Foresters, finding that conifer seedlings were tolerant to the refined oils, sprayed forest tree nurseries. Research proved that a somewhat less toxic oil could be used on flax and onions. The use of refined selective spray oils found a definite place in the agriculture of our country. 

Experiments were conducted at Cornell in an attempt to learn more about the effects of temperature on oil toxicity. Small carrot and parsnip plants were placed at four temperature levels 40 to 50 , 50 to 60 , 60 to 70 , and 70 to 80 F. After 2 weeks at these temperatures, one sixth of the plants in each group were sprayed at the rate of 80 gallons per acre with a Stoddard solvent (Varsol No. 2) which contained an additional 4% diethylbenzene. One week after the first treatment a second lot of plants was sprayed in the same manner. Ten replications of carrots and five replications of parsnips were used. Harvests were made 2 weel after the treatments. 

Minshall and Helson (7) of the Dominion Department of Agriculture at Ottawa, Canada, have studied the physiological action of petroleum naphtha on carrots, parsnips, and several weeds including mustard. They used infrared absorption apparatus, and by means of readings taken at 10-second intervals following oil application, determined that photosynthesis ceased abruptly for all plants studied. With parsnips, photosynthesis was resumed within 30 minutes after application it was one third of norm at the end of 3 hours, and at the end of 48 hours reached approximately the original rate before treatment. Parsnips did not wilt following treatment. The common mustard plant had a... 

The respiration rate of parsnip continued for at least 3 hours with little change after application, increased slightly thereafter for 5 days, and then returned to normal in the oil-sensitive mustard, it continued for only 1 hour at the original rate, and thereafter tapered off gradually to zero some 2 hours after oil treatment, by which time the leaves were dead. 

Reactions may be seen to Cynara scolymus in market gardeners [224], food handlers, vegetable sellers [225], and workers cleaning artichokes [223], and to parsley and parsnip in kitchen workers [201, 204, 205]. In Japan, persons who wrap leaves of the beefsteak plant, Perilla frutescens (shiso) are prone to develop allergic contact dermatitis, apparently from L-perillaldehyde [226]. Mustard caused contact dermatitis in a salad maker [227]. Patch testing can be done with synthetic oil of mustard [228] (0.1% allylisothiocyanate). 

Butyric acid or fermentation butyric acid is also found as a hexyl ester (hexyl butanoate) in the oil of Heracleum giganteum (a type of hogweed) and as an octyl ester (octyl butanoate) in parsnip Pastinaca saliva), it has also been noticed in the fluors of the flesh and in perspiration. 

Oil of parsnip contains a considerable amount of esters of octylic alcohol. 

TIP Peel and wash vegetables such as carrots, onions, celery, potatoes, yams, parsnips, and turnips, and cut them into like-size chunks. Toss with olive oil and put them on a baking sheet, in a single layer. Sprinkle with salt and pepper. Roast the vegetables on a different rack while your chicken roasts, and you ll have a complete meal when it s done.
