Zinc is used in the plant in conjunction with other essential nutrients for stimulation of various enzyme systems. Zinc deficiency severely depresses photosynthesis.
Maize, Potatoes, top fruit, Hops, Linseed, Barley and Beans are particularly sensitive to zinc levels. Sandy soils, high pH soils and soils with high phosphate level can limit the availability of zinc. Low temperature and wet conditions also limit the uptake of zinc. Low temperatures frequently occur during the early stages of development of maize and it is essential that adequate zinc is available.
- 690 g/l zinc (Zn).
- Suspension concentrate.
- RATES OF USE
- Apply Zinc FL at 1 l/ha. Repeat applications at 10-14 day intervals if required or as indicated by tissue analysis. Do not apply to protected crops. Use at least 200 litres of water per hectare. Increase the water volume as necessary to ensure good cover of the foliage.
- Zinc is formulated with buffering agents and a modern surfactant system to ensure stability and effective cover and adhesion to foliage.
- RATES OF USE AND TIMING
- Zinc FL is a ready-to-use liquid containing zinc formulated as a suspension concentrate, for correction of zinc deficiency in a wide range of crops. It contains an advanced surfactant/suspension system to ensure rapid and even dispersion in the spray tank and superior adhesive properties on foliage.
- Cereals:apply from the 3-leaf stage.
Oilseed rape, leaf and root brassicas, sugar beet, maize: Apply from the 4-6 leaf stage.
Peas and beans: Apply from the commencement of flowering.
Potatoes: Apply from full emergence.
Other crops: Apply when there is sufficient foliage present to retain the spray.
Headland recommends that soil and tissue analysis results are used whenever possible to guide micro and macronutrient applications to optimise crop nutrient status. Do not apply this product in very bright sunlight or in temperatures above 25°C. If possible, spray in the evening or early morning for best results.
