Not with herbicides at early stages — caution

Overview

About this product

Quantum Manganese Chelate (Mn) — a concentrated micronutrient fertilizer with a special manganese formulation and biologically active substances, which, per the maker, ensures their high availability. It contains 65 g/l of manganese; pH 5.5–7.5, density 1.28–1.33 kg/l.

It is intended for crops sensitive to manganese shortage. As a foliar it is applied at 0.7–1.2 l/ha on wheat, barley, maize, soybean, pea, sunflower, oilseed rape and beet, and on fruit, berry and vegetable crops at the same rate at 14–21 day intervals.

In fertigation 100 ml per 1 m³ of water, In-Furrow with Quantum Diafan ACTion 1–3 l/ha.

With manganese deficiency (by visual or laboratory diagnosis), for all crops, especially fruit, berry and vegetable crops, treatments are repeated at 7–10 day intervals

Method: Foliar feeding with standard sprayers: spray solution 200–400 l/ha for vegetable crops, 500–1000 l/ha for grapes and fruit crops
Fertigation on drip irrigation: 100 ml of product per 1 m³ of water
Conditions: Prepare the spray solution immediately before application: fill the tank 2/3 with water and, while stirring, add the components one at a time, waiting until the previous one is evenly mixed
Spray in the morning or evening; optimal air temperature 10–25 °C, wind up to 5 m/s
Tank mix: Joint application with plant protection products and other fertilizers is possible, but do not combine feeding with herbicide treatment at the early stages of plant development
Before mixing, check compatibility: a test spray solution must not form a precipitate, slight turbidity is acceptable
