Decomposes on heating. This produces nitrogen oxides (see ICSC 0067, ICSC 0930) and hydrogen chloride (see ICSC 0163). Reacts with strong acids, strong bases and strong oxidants. This generates fire and explosion hazard.

Storage stability: a minimum of 2 years

Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered.

AEROBIC: Possible pathways for aerobic primary degradation of picloram are decarboxylation or amino displacement(1). Soil half-lives for picloram at various initial concentrations were 55 days at 0.25 ppm (7 days lag-phase), 90 days at 0.5 ppm (30 days lag phase), and 180 days at 1.0 ppm (90 days lag phase)(2). Picloram was degraded through aerobic metabolism in seven soils, half-lives ranging from 167 to 513 days, with carbon dioxide being the major degradate(3). Aerobic degradation half-lives for picloram at various application rates were 18 days at 0.0025 ppm, 29 days at 0.025 ppm, 150 days at 0.25 ppm, and 300 days at 2.5 ppm(4). After 100 days incubation in 3 soil types, remaining picloram concentrations were 63 to 77% of the initial concentrations(5). Degradation of 75 to 100% picloram in soils required 18 months(6). No detectable degradation of picloram was observed in 8 weeks in soil with high organic matter content from Pentego, NC(7). In the presence of a mixture containing 0.5% fertile garden soil, yeast, and other organics, picloram persisted >275 days(8). In a 423 day period using a picloram concentration of 0.4 ppm, some soils had 52 to 82.5% of the picloram decomposed and others had only 5.2 and 7.6% decomposed(9). Degradation of picloram in thirteen soils after incubation for 6 months ranged from 0 to 60% at 3 mg/L, from 0 to 84% at 1.5 mg/L, from 5 to 94% at 0.75 mg/L, from 28 to 99% at 0.375 mg/L, from 38 to >99% at 0.188 mg/L, from 32 to >99% at 0.094 mg/L, from 28 to >99% at 0.047 mg/L(10). Most of the soils showed a tendency towards greater percentage detoxification for lower concentrations(10). Picloram was applied at a rate of 10 ppm to five different soils, after 124 days of alternating wet and drying cycles, picloram remained in the soil 82.7 to 91.0% incubated at 30 deg C and 86.0 to 93.0% incubated at 50 deg C(11). The amount of non-degraded picloram in groundwater from 4 sites after incubation for 15 weeks (105 days) was 60.8 to 82.4% (average 71.6%) at an initial concentration of 0.72 ppm, and 60.7 to 79.8% (average 67.9%) at an initial concentration of 10.0 ppm(12).

BCFs of 0.11 and 0.54 were reported in bluegill sunfish exposed for 28 days at C14 labeled picloram concentrations of 1.0 and 0.1 mg/L, respectively, using a flow-thru system(1). The BCF of picloram in fish was also measured as 31 using the flowing water method(2-3). According to a classification scheme(4), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).

Experimental Koc values for picloram are 12.7(1-2), 25.2(3), 0.026(4), 17(5), and 25.5(6). Koc values for picloram in soils were 11.1, 22.1, 11.2, 12.5, 18.0, 20.6 and 9.9 at 0.74, 2.92, 1.03, 1.36, 0.45, 1.89, and 1.17% organic carbon, respectively(7). Koc values for 28 different types of pasture soils with varying amounts of organic carbon ranged from 14 to 100(8). According to a classification scheme(9), these Koc values suggest that picloram is expected to have very high to high mobility in soil. The pKa of picloram is 2.3(10), indicating that this compound will exist almost entirely in anion form in the environment and anions generally do not adsorb more strongly to organic carbon and clay than their neutral counterparts(11). Leaching potential is greatest in sandy soils low in organic matter(12-13). Picloram is usually confined to the upper 1 foot (30 cm) when application rates are low (<1 lb/acre, <1.12 kg/ha), but that picloram can readily move to depths >3 feet (approximately 1 meter), even in relatively dry areas, when the application rate is high (3 to 9 lb/acre, 3 to 10 kg/ha)(16).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
