The product is recommended for foliar application and in hydroponic systems. Application to the soil is possible, though foliar feeding is preferred.
In soil conditions Mn can be easily replaced by iron at the EDTA complex. Therefore best results are obtained when iron contents in the soil and irrigation water are low, otherwise foliar application is recommended. Dissolve in water and apply to the soil close to the plants or trunks. After each application water carefully to enhance nutrient uptake. Application must be made in a way that ensures the solution to reach the roots. Lidoquest Manganese EDTA 13% is totally water soluble and therefore very suitable for fertigation
In hydroponics Lidoquest Manganese EDTA 13% improves the efficacy of Fe-chelates. Though the pH in the irrigation water is around pH 6, the pH in the fertilizer tank can be very low. Lidoquest Manganese EDTA 13%is stable from pH 3 - 10. Never bring Lidoquest Manganese EDTA 13% in direct contact with concentrated acids.
Vegetable crops (tomato, cucumber etc.) do need 10 µmol Mn/l (0.55 ppm) continuously, flower crops 5-10 µmol Mn/l (0.27-0.55 ppm). Consult table A for equivalents in grams of product.
Foliar feeding provides a rapid response and is recommended when fast correction is necessary or soil application is expensive and impractical, or impossible, for example if the soil is extremely wet. Repeated applications might be necessary. For improving leaf coverage it is advisable to add a wetting agent, efficacy may be further increased by adding urea. Dissolve the product to a suitable concentration, and apply with spraying equipment. The pH of final concentration should be lower than 6.5, the final EC lower than 1. Dose rates for a specific crop should be tested first on a small scale. When manganese deficiency is severe, a repeat application should be made after 2 weeks. Start treatment in early growth stage, but in general apply when there is sufficient leaf area to absorb the spray. To reduce the risks of leaf scorching avoid application during hot, sunny days. Treatments in the early morning are preferred.
The product can be mixed with most other fertilizers and agrochemicals without inactivation, precipitation or scorching problems. Do not mix with chemicals based on metal compounds. With liquid fertilizers use the mixture without delay. Test mixed product first on a small scale.
Add the required amount of product to a half filled sprayer tank, then complete the filling process. Ensure that sprayer nozzles are adequate for 200-1000 liters water/ha. Use the higher volume under dry conditions, when treating larger crops and at dense foliage.
No health hazards are involved in normal handling of Lidoquest Manganese EDTA 13% but it is advisable to follow the above precautions.
Apply pre-drilling or pre-planting
to bare soil in a convenient volume of
water, cultivate after spraying
Apply through the watering system.
Use enough water to wet the top 10 cm of the soil.
Use clean water immediately afterwards to wash the
manganese chelate from the foliage.
Or use the last 5 minutes the foliar application rate.
Apply in a water volume
that gives adequate coverage
of the crop (200-1000 L).
Do not exceed a concentration of 0.1%.
