3 ACTIVE INGREDIENTS: 600 g/L triclopyr as the butoxyethyl ester

4 CHEMICAL GROUP: I. Pyridine

5 RELATED HERBICIDES:

Lontrel, picloram, Starane

6 GENERAL DESCRIPTION:

A translocated, leaf absorbed herbicide used mainly for the control of woody broadleaf weeds. Established grasses are not usually affected at normal use rates.

7 APPLICATION METHODS AND TIPS:

Apply to actively growing weeds.

Maximum tank storage time - 1 week.

9 ADJUVANTS:

Spray oils and Pulse Penetrant are often useful for hard to kill species.

Non ionic wetting agents should be used in for most other applications.

The concentration of Pulse Penetrant should be in the range of 0.1-0.25% of spray solution (Field et al 1995).

Uptake, D-C-Trate, D-C-Tron, Winter Spraying Oil, Summer Spraying Oil and BS 1000 are compatible.

Synertrol is not recommended.

20 MODE OF ACTION:

Uptake and translocation:

Absorbed by leaves and roots and is readily translocated throughout the plant.

Physiological effects:

Disrupts the growth of plant cells.

Residual Life and Breakdown:

Selectivity:

Most broadleaf species affected and most grasses unaffected.

23 PLANT SYMPTOMS:

Produces typical auxin or hormone types symptoms including twisting, cupping and narrowing of the leaves and deepening of the sinuses.

SECONDARY EFFECTS:

24 TOXICITY:

Summary:

Moderately toxic.

Details:

Mammalian toxicity

Acute oral LD50 - 713 mg/kg (rats), [For comparison table salt is 3000 mg/kg]

Acute dermal LD50 - > mg/kg (rabbit).

Skin -

Eye - Slightly irritating.

Vapour inhalation - LC50 - > mg/L air (rat).

Chronic oral toxicity NOEL - ppm for two years.

Other Species -

Birds - Low toxicity.

Fish - Very low toxicity LC50 > ppm.

Invertebrates - toxicity.

Bees - toxicity.

25 TOXICITY SYMPTOMS:

26 FIRST AID:

27 ENVIRONMENTAL FATE:

Triclopyr is broken down mainly by microbial activity in soil.

It has a half life in soil of 10-46 days.

It has an EPA classification for soil mobility that ranges from

Ground water contamination

Replanting intervals are less than 12 months.

Accumulation in milk and tissues.

31 PROPERTIES:

Odourless white solid.

Water solubility at 25 C. - 430 ppm at pH 7;

Oil solubility - Very soluble in ethanol, slightly soluble in benzene.

Octanol:Water ratio at 250C. - at pH 5;

Vapour Pressure at 250C - 1.26 x 10-6mm Hg

Dissociation constant - pKa

Melting point - 148-1500C. Decomposes at 2900C.

Molecular weight - 256.48g

Half life in water - days at pH5 and 35 C.

The ester formulations are usually more active than the amine formulations.
