NOTE: These Directions for Use form part of the Approved Product label and must be read before using the product. MALVI is a protectant fungicide from the dithiocarbamate group. As a protectant fungicide it should be applied before blight becomes established in the crop. Spray programmes often start before the foliage meets across the rows, often mid-June but take note of blight warnings issued in your area. If applications are delayed, or where blight is detected in the crop, application in mixture with a fungicide such as one containing cymoxanil will give some eradicant activity and will help to delay further development of blight in the crop.

 

The active ingredient in MALVI is mancozeb and, while blight is a disease known to rapidly develop resistance to some fungicides, mancozeb has multi-site activity on the fungus that causes blight and therefore forms part of a sensible anti-resistance strategy. However, to protect this activity, it should be used as part of a programme of treatments that incorporate a number of different modes of action. The FRAC mode of action code for mancozeb is M3. Use MALVI in programmes containing different mode of action codes.

 

MALVI should be applied at a dose rate of 2.13 kg/ha in a water volume of 200 – 1000 L/ha as a FINE or MEDIUM spray as defined by BCPC. MEDIUM spray qualities should be used for the higher water volumes necessary for the larger crop canopies. Repeat applications of further blight spray programmes at 10 – 14 day intervals. When blight pressure is intense, the spray interval can be reduced to 7 days but 7 days is the minimum between applications of MALVI or other sprays containing mancozeb. A maximum of 8 applications is allowed and the final spray must be at least 7 days before harvest.

Note that irrigated crops carry a higher risk of developing blight because of the increased humidity within the crop canopy. Apply MALVI shortly after irrigation when the crop foliage has dried.

 

Before spraying it is important to check all hoses, filters and nozzles, and to ensure that the sprayer is clean and correctly set to give an even application at the correct volume. Cream the required amount of MALVI with a little water in a separate container and then add more water to form a thin cream with no lumps. Add this cream to a spray tank half filled with water. Rinse the container into the tank, start the agitation and then add the rest of the water. Maintain agitation and spray immediately after mixing. After application, rinse out the sprayer with a minimum of two rinses to remove residues from the tank and hoses using a proprietary sprayer cleaner.
