EDTA-Cu15 should be dissolved in a convenient volume of water to suit the application equipment and to ensure even ground coverage.
For general crops, apply as a coarse low pressure spray immediately before the last cultivation prior to sowing or planting. Where crops are established, apply between the rows. Applications should be incorporated into the top few centimeters of soil as soon as possible after application.
For perennial crops, apply as a coarse low pressure spray in a wide circular band under the limit of the full branch spread. For best results, nutrients need to be in the root zone before seasonal growth begins and this can be achieved by appropriate application timing.
Application rates *
Farm crops 0.5 - 2.0 kg per ha
Trees 7 - 30 grams per tree
Shrubs 0.1 - 0.7 kg per 100 bushes
Soft fruit 0.1 - 0.3 kg per 100 plants
*Depending size, degree of deficiency etc
Application rates, general
EDTA-Cu15 may be applied in one application of 1.0 kilograms per hectare but optimum results can be expected if repeat applications are used. In general, foliar applications should be started early in the season as soon as there is sufficient leaf area to absorb the spray.
Application rates, specific
|Winter Cereals||0.25 - 0.50||Apply when spring re-growth commences. For severe deficiency, an additional full rate application soon after tillering (ZCK 23).|
|Spring Cereals||0.25 - 0.50||Apply as soon as there is sufficient leaf area to absorb the spray.|
|Sugar Beet||0.25 -0.5||With repeat dose herbicide programmes, apply with each application.|
Conventional application as soon as there is sufficient leaf area to absorb the spray.
|Peas||0.25||Apply just before or at flowering and repeat if necessary 10-14 days later.|
|Top and Soft Fruit||0.25||Begin application in early spring and repeat as necessary throughout the season.|
|Pasture||0.25 0.5||Apply in early spring, the treatment should be repeated annually.|
Statutory Caution: To be used only where there is a recognized need. Do not exceed the appropriate dose rate.
No health hazard is involved when EDTA-Cu15 is used as directed
No special precautions are necessary for transport by air, sea, rail or road.
