6 GENERAL DESCRIPTION:Diclofop is a selective and translocated herbicide that is absorbed through both leaves and roots. Its main use is for controlling annual ryegrass and wild oats in wheat, barley and broadleaved crops and pastures. Toxicity to mammals and birds is low but it is toxic to fish. In land environments it presents few environmental hazards because of its low mobility in soil, low volatility, low toxicity and reasonably quick degradation in soil and water. Direct application to aquatic ecosystems should be avoided. Application to flood irrigated areas or similar may lead to contamination of water. Plants are likely to become resistant to diclofop after repeated applications.
7 APPLICATION METHODS AND TIPS:Diclofop is normally applied in water with wetting agent as a post-emergence spray by boom sprays or aircraft. It is most effective when applied to actively growing plants. Plants under drought stress are very difficult to kill with diclofop. Ryegrass or wild oat plants in the two leaf stage are more susceptible to diclofop than older or younger plants. Successful control has been achieved on dewy and frost covered crops but it is recommended to avoid these conditions if possible.
11 COMPATIBILITY:Hormonal herbicides such as 2,4-D are antagonistic. 2,4-D decreases the conversion from the ester to the active acid form, decreases translocation of diclofop, increases the rate of detoxification and competes at the fatty acid synthesis level. Plants treated with 2,4-D up to two weeks before or after diclofop application may be less susceptible to diclofop. MCPA antagonism is different and appears to be caused by reactions outside the plant.
14 HERBICIDE RESISTANCE:Ryegrass and wild oats that are tolerant to diclofop occur naturally at low levels. After four or five annual applications of diclofop a significant level of diclofop tolerance would be expected if no other form of weed control was practiced.
20 MODE OF ACTION:Diclofop is absorbed through the foliage and roots of nearly all plants. In susceptible plants it is converted from the ester to the biologically active acid form. Typically, less than 10 per cent of this is translocated in the phloem and xylem to accumulate in the growing tips. Cell division and elongation are stopped resulting in the stunted appearance of treated plants. Membranes are disrupted giving a 'water soaked' appearance. Fatty acid synthesis is stopped resulting in the death of growing tips, hence leaves of treated grasses can be easily pulled from their sheaths. Plants tolerant to diclofop appear to have a different fatty acid synthesis mechanism, degrade diclofop more quickly and do not convert as much of the inactive ester to the active acid form. It is normally, used as a post emergence herbicide but does have some pre emergence activity at high rates. Wild Oats and Annual Ryegrass germinating soon after spraying are often stunted.
23 PLANT SYMPTOMS:Annual ryegrass and wild oats stop growing soon after application. The leaves take on a water soaked or oily appearance within a few days. About a week later, leaves become red-brown in colour and may be easily pulled from their sheaths before dying. Plants that recover have severely reduced root systems.
24 TOXICITY:Mammalian toxicity - low.
27 ENVIRONMENTAL FATE:Diclofop is strongly adsorbed on soils. Its solubility provides a slight risk for movement into ground water under extreme conditions. It is broken down in plants. In soil, microbes break down diclofop with a half life of around 28 days. At higher pH and under anaerobic conditions the half life is increased. Diclofop is rapidly excreted from animals and does not move into milk or eggs. It is not degraded by light.
