The use of toxic polynitro derivatives in pest control III. The stability of dinitro‐o‐cresol in compounded products

Abstract
Under certain conditions dinitro‐o‐cresol (D.N.C.) is easily decomposed to reduction products devoid of ovicidal properties to eggs of apple sucker, winter moth and fruit tree red spider.Because of this, corrosion of containers in which D.N.C. products are stored may be accompanied by a deterioration of the product.At the concentration normally used in winter washes (0.1%), D.N.C. is equally effective whether present as cresol or as the sodium cresylate against eggs of apple sucker and of winter modi, but against eggs of fruit tree red spider the cresol is more ovicidal than the cresylate.
