“…In contrast to our results, they observed that ammonium nitrate had little or no effect on the stability of the insecticides, but this is not surprising in view of the fact that they were working with Endrin and similar compounds which are not as readily oxidized as Di-Syston. Fleck and Haller (1945) have observed that no fertilizers except dolomitic limestone showed catalytic activity when placed in contact with DDT. Instability of insecticides in fertilizer mixtures has also been related to minor characteristics of the fertilizers, such as iron content and surface acidity (Beilin et al, 1956).…”

“…Volatility may also cause measurable long-term losses, particularly in the surface layer under high-temperature summer conditions. Catalytic decomposition of DDT in the presence of clay minerals and inorganic salts, notably those of iron, aluminium, and chromium, has been reported by Fowkes et al (1960) and by Fleck and Haller (1945). A number of New Zealand soil types has been examined for catalytic effects, and it has been possible to show that certain soils derived from volcanic ash showers promote decomposition at elevated temperatures.…”

DDT is applied to pasture in conjunction with superphosphate, for the control of damage by soil insects, particularly grass-grub (C ostelylra). In a plot trial on Papatoetoe silt loam, DDT penetrated to a maximum depth three months after application. Most of the insecticide recovered was associated with the top 2 in. of soil. Decomposition of DDT appeared to take place solely within the top 1 in. of soil, approximately 50% loss being observed in the initial 12-month period of the trial. No significant difference in distribution pattern or breakdown rate could be detected hetween rates of application ranging from 1 to 8 lb pp'-DDT per acre.

“…Thus, the work of Marth, Hardesty, and Mitchell (42) and of Muller (47) indicates that 2,4-D added to superphosphate and mixed fertilizers largely retains its potency even under rather adverse conditions of preparation and storage of the products. According to Fleck and Haller (22), DDT is stable in contact with several fertilizer materials and mixtures at elevated temperatures, at least for short exposures, but it is catalytically decomposed by dolomitic limestone. Aldrin, chlordan, and perhaps dieldrin and heptachlor are variously reported (8,77,25,38) to be compatible with fertilizers and to be stable in mixtures, but experimental evidence in support thereof appears to be lacking in the literature.…”
