To complement the very successful Kick-Off Fielder has launched four new biostimulant manganese-based seed treatments. These products are true solutions, are safe to germinating seed and totally miscible with any simultaneously applied seed treatments. Available inn a range of pack sizes for application through static or mobile seed treatment equipment.

Manganese ST

A true liquid manganese formulated in the sulphate form with well proven properties of seed safety and speedy uptake by the germinating seed. This 15% formulation applied on cereals at 4l/ha provides sufficient manganese to assist in crop establishment and early development in manganese deficient soils. Easy and safe to apply in conjunction with other essential agrochemical seed treatments.

Manganese Duo (manganese + copper - 10% Mn + 1% Cu)
Manganese Duo (manganese + zinc - 12% Mn + 0.5% Zn)

Based on manganese sulphate but including copper or zinc for additional benefits where soils may be low in these nutrients. Copper deficiencies often occur in the sandy peaty soils which are also low in manganese. Zinc is again vital in helping early root development.

Manganese Trio (manganese + copper + zinc - 10% Mn +1% Cu +0.5% Zn)
The Rolls Royce manganese product containing  all three nutrients. The lower percentage of manganese is necessary to accommodate both copper and zinc and to maintain levels available to the seed the application rate for cereals is increased to 5l/tonne


Fielder Humic Acid

Humic acid and fulvic acid are the final breakdown products of natural decay of plant and animal material. Fielder Humic Acid provides a concentrated dose of essential nutrients, vitamins and trace elements including N, P, K, Ca, Cu, Zn, Fe, Mn, Co, S, B, I, If applied in conjunction with fungicides and nutrient products they act as a chelating agent improving uptake and utilisation.

In the plant they stimulate plant enzymes and act as a catalyst for many biological processes. Hence growth is increased by accelerating cell division, chlorophyll development is promoted aiding photosynthesis and natural resistance to pests and diseases is enhanced.

Fielder Amino Acid Complex

A natural biostimulant derived from molasses and vegetable materials. Fielder Amino Acid contains 19 amino acids which are vital to all plant processes such as photosynthesis, nitrogen uptake, protein and carbohydrate synthesis. Applied at 1-3 litres/ha and tank miscible with most agrochemicals and foliar nutrients.

Stretchur N

A phased release nitrogen consisting of urea polymers of varying lengths to release nitrogen more efficiently than ammonium nitrate and provide the plant with a continuous supply to convert into plant protein. The product contains 28% N and is applied at 10-20 litres/ha.

In trials on maize at Harper Adams Stretchur N has produced a 7% increase in digestible yield.

Slicker (silicon +potassium)

Silphite (silicon + phosphite)

Both of these products are based on silica which is well known for increasing cell wall toughness and thus increasing standing ability and resisting penetration by sucking insects and fungal hyphae. It also helps regulate transpiration and water loss. Work in cereals has shown 0.4tonnes/ha yield responses. In conjunction with potassium heat and drought stress are reduced and frost resistance is increased. With phosphite root development is enhanced.
