DISEASES CONTROLLED
APRON XL is an emulsion formulation for seed treatment containing 339.2 g/l metalaxyl-M. The product is intended for use as a seed treatment for protection against infestation of Pythium spp. in a range of vegetable crops.

CROP SPECIFIC INFORMATION

 

For the control of Pythium spp. Limited data indicates that in spinach activity against Pythium spp. can be variable depending on the composition of the population. During the period December until February the soil should be covered after drilling to encourage germination. This could be either fleece or a plastic   tunnel.

Dose rate: 0.5 ml APRON XL per kg of seed.

For the control of Pythium  spp

Dose Rate: 0.5 ml APRON XL per kg seed.

 

Timing
Before drilling

MIXING AND APPLICATION
APRON XL should be applied through continuous flow or batch seed treaters. Adequate seed coverage should be obtained if APRON XL is added during the mixing of the seeds. Calibration of the dose rates needs to be done before use. The method depends on the equipment used. Consult the manual for the machine or seek further advice from Syngenta. The treatment equipment used should be a closed system in order to minimise the risk of contact with the product. Safety precautions should be followed throughout.

APRON XL is usually applied during the process of pelleting vegetable seeds. Pelleting requires specialist equipment. If necessary Syngenta UK Limited can be consulted for advice on application during the pelleting process.

Mixing Procedure
1. Calculate the quantity of seeds to be treated.
2. Calculate the dose rate of product to be applied.
3. Prepare the mixture. It is normal to use a mixture of 50% water to 50% product but this also depends on the application machinery being used. A dilution rate of four parts water to one of product is usually the maximum dilution rate used.
4. Ensure that there is good agitation to keep the product evenly suspended.
5. Ensure that the application equipment is properly calibrated for the seed to be treated.
6. Apply the product. Do not leave the mixed slurry for any period without agitiation.

Storage after Treatment
Ensure seed is of a satisfactory moisture content before storage. Keep in a dry place, correctly labelled.
Treated seed not drilled in the intended season of use may be stored for drilling one season later. Stored seed should be kept secure in a cool, dry location.

Drilling
The sowing/drilling method appropriate for the crop should be followed. APRON XL does not have any known adverse effect on the drilling method.

Resistance: APRON XL contains a phenylamide fungicide. A number of diseases, including Pythium species, have developed resistance to phenylamides. Strains of diseases including “downy mildew” resistant to the phenylamide group of fungicides, which includes metalaxyl-M are known to occur in some regions of the United Kingdom. Where strains of pathogens resistant to metalaxyl-M develop APRON XL may not give satisfactory control of the disease. Where there is a known resistance problem with metalaxyl-M growers should seek other methods of disease control. While fungicides such as metalaxyl-M are an important tool for minimising the effect of pathogens on crops growers should always seek to combine fungicidal seed treatment with appropriate cultural methods for reducing diseases. Clean healthy seed should be used, and where possible, varieties should be selected which offer resistance or tolerance of commercially important pathogens. Use of these techniques should also be supported by optimising the growing conditions for the crop so as to minimise the impact of pathogens on the health of the crop.
