ActivityFungicide
Trifloxystrobin is active against ascomycetes, basidiomycetes, deuteromycetes and oomycetes, especially in the early stages in the infection cycle. Novartis coined the term ‘mesostemic’ to encapsulate all aspects of the product's activity on and in plants. Trifloxystrobin is applied to foliage and is strongly adsorbed to the waxy, cuticular layer of plants. Product that remains on the leaf surface acts as a protectant. Some product penetrates the cuticle and remains either just below the surface to provide curative activity or is distributed locally providing translaminar activity. However, it is not translocated in the vascular system.
It is safe to crops and shows no cross-resistance to fungicides from other chemical classes. The product has a greening effect on cereals that leads to increased yields.
Physiological studies into the effects of trifloxystrobin on the yield and protein content of wheat indicate that enhanced nitrogen metabolism may explain the maintenance of protein levels at higher yields, thus avoiding the dilution effect shown by other strobilurins (Pflanzenschutz-Nachrichten Bayer, 55). Trifloxystrobin, azoxystrobin and kresoxim-methyl increased flag leaf area, but levels of nitrate reductase were only increased by trifloxystrobin. In field trials, trifloxystrobin treatments extracted more soil nitrogen. No strobilurin affected photosynthesis, but only trifloxystrobin decreased transpiration, which suggests more efficient use of water.
It is recommended that trifloxystrobin is used primarily in a preventative spray schedule.
Trifloxystrobin also has activity via movement in the vapour phase, which contributes to disease control within the crop canopy.
In field trials, trifloxystrobin often gave better disease control than standard fungicide treatments (including other strobilurins) at similar or lower application rates. Novartis UK trials showed that crops treated with Twist out-yielded those treated with azoxystrobin in 67% of trials and those treated with kresoxim-methyl in 94% of trials. It is also stated that trifloxystrobin offers superior control of Septoria tritici and S nodorum on wheat, and Rhynchosporium secalis on barley compared to other strobilurins although the control of yellow and brown rust on wheat and brown rust and net blotch on barley is inferior to that given by azoxystrobin. In field trials carried out on cotton in the period 1997-2001, trifloxystrobin tank mixed with mefenoxam (D0082) was found to increase stand counts compared to other standard fungicides. Although there was no significant increase in yield, trifloxystrobin was found to control significantly more seedling disease.
Trifloxystrobin (code number USF 2004) has been tested in the US at 105 ml/ha plus 122 ml/ha of tebuconazole on cantaloupe and although it provided ‘fair’ control of powdery mildew, it was not as effective as triflumizole (D0001L). It has also been tested in combination with Induce (2.5 oz/a USF 2004 + 0.25% Induce) on powdery mildew in Kentucky bluegrass (NuGlade) with good results. USF 2004 (at 2 and 2.5 oz/ac) has been found to reduce the incidence of choke on Tiffany Chewings Fescue when used in combination with Folicur (2.31 and 2.88 oz/ac) and Induce (0.25%). It is also moderately effective for control of greasy spot (the efficiency is increased by the addition of petroleum oil) and melanose (in combination with copper products) on grapefruit.
In cereals, trifloxystrobin should be used in mixtures with triazoles; the company recommends mixtures with cyprodinil (D0037), cyproconazole or epoxiconazole (D0019). In fruit and vegetable crops, the product should be used as part of a spray programme alternating with fungicides with a different mode of action. The company states that trifloxystrobin is suitable for use in IPM programmes.
In vines, trifloxystrobin is active against black rot (Guignardia bidwelii), powdery mildew (Oidium spp), excoriose (Phomopsis viticola) and rotbrenner (Pseudopeziza tracheiphila), and demonstrates secondary effects against Botrytis. Residual activity is maintained for around 14 days.
Field trials conducted in turf (APS, 2002) showed that Compass or applications of trifloxystrobin plus fosetyl-Al or triadimefon provided good control of rapid blight. This disease has recently been identified as a potential major problem in turf where it can kill large areas of perennial ryegrass and rough bluegrass that are overseeded onto bermudagrass golf courses.
USF 2007 and USF 2010 are combinations of trifloxystrobin + tebuconazole. In 2001 and 2002, USF 2007 was tested on sugar beet for the control of cercospora leaf spot (cercospora beticola) and in 2002 on potato for the control of early blight (Alternaria solani). The results were comparable with those of other fungicides under evaluation. In 2003, USF 2010 was tested on almonds, peaches, peanuts, and sour cherries for the control of a variety of diseases, including brown rot, early and late leaf spot, leaf curl, powdery mildew, rhizopus rot, rust, rusty spot, scab, southern stem rot, web blotch. In most tests, the product compared well with other commercially available fungicides. -

Fate in aquatic systems:
Hydrolysis occurs at pH >5. In surface water, trifloxystrobin is rapidly degraded within a few hours by microbial processes.Fate in soil:
Trifloxystrobin is degraded by microbial and photolytic processes in soil. It has a soil half-life under field conditions of 2-16 days. The product adsorbs strongly to soil particles (Koc = 1642-3745 ml/g) indicating limited potential for mobility in soil. The acid metabolite, CGA-321113, appears to be a mobile and persistent metabolite which is degraded at a slower rate than the parent compound. -
