Cropmax is an ultra-concentrated foliar fertilizer and plant biostimulant formulated with plant growth promoters, amino acids, vitamins, enzymes, polysaccharides, macro nutrients and trace elements.

It is designed to support root development, vegetative growth, flowering, fruit development, nutrient uptake and plant recovery from environmental stress. Cropmax is suitable for a wide range of crops and can be used throughout the growing season. The manufacturer recommends a general application rate of 0.5–1 litre per hectare.

Product Overview

Cropmax combines foliar nutrition with naturally occurring plant growth-promoting compounds. Its formulation contains auxins, cytokinins and gibberellins, together with amino acids, vitamins, enzymes and mineral nutrients.

Unlike a conventional high-analysis NPK fertilizer, Cropmax is primarily intended to stimulate plant physiological activity and improve the efficiency with which the crop uses available nutrients.

According to the manufacturer, Cropmax promotes rapid root development and vegetative growth, improves nutrient utilisation, supports photosynthesis and helps plants withstand stresses such as drought and high temperatures.

Key Benefits

• Promotes rapid development of the root system
• Encourages vigorous vegetative growth
• Supports flowering and fruit development
• Helps improve plant nutrient uptake and utilisation
• Supports photosynthetic activity
• Helps plants recover from environmental stress
• Supports tillering and branching
• Can improve the efficiency of conventional fertilizer programmes
• Suitable for vegetables, fruits, cereals, oilseeds and other crops
• Can be tank-mixed with many pesticides and fertilizer solutions, subject to compatibility testing

The manufacturer also describes Cropmax as suitable for organic agriculture and reports compatibility with pesticides and fertilizer solutions.

Cropmax Composition

Composition per litre of product:

Cropmax also contains a spectrum of amino acids including alanine, arginine, asparagine, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tyrosine and valine.

How Cropmax Works

Cropmax is intended to act as both a foliar nutrient supplement and physiological growth stimulant.

The manufacturer describes three important effects:

1. Root stimulation
Cropmax stimulates root development, helping the plant explore a larger volume of soil and make better use of available nutrients.

2. Improved nutrient movement
Its systemic activity is described as supporting redistribution of nutrients and reserve compounds towards actively growing plant tissues.

3. Support during stress
The growth regulators, amino acids and associated compounds are intended to help maintain plant physiological activity when crop growth is affected by heat, drought or other stresses.

Application Rate

General Rate

0.5–1 litre per hectare per application

Approximately:

• 0.5 L/ha ≈ 200 ml/acre
• 1 L/ha ≈ 405 ml/acre

Use the rate appropriate to the crop and growth stage.

Spray Water Volume

The manufacturer recommends approximately:

150–500 litres of spray solution per hectare.

Good spray atomisation and thorough crop coverage are recommended for effective foliar uptake.

Crop-Specific Application Examples

Maize / Corn

Apply around:

• 8–9 leaves: 0.5 L/ha
• 10–12 leaves: 0.5–1 L/ha depending on production intensity

Cereals

Applications may be made around:

• Start of tillering
• End of tillering
• Ear emergence

Typical rate: 0.5 L/ha per application.

Sunflower

Typical timings include:

• 5–7 pairs of true leaves
• Budding

Rates in the manufacturer programme range from 0.5–1 L/ha.

Potatoes

Recommended stages shown in the manufacturer's programme include:

• Leaf development
• Flowering

Rate: approximately 0.5–1 L/ha, depending on the production programme.

Onions

The brochure indicates an application during bulb growth at approximately 0.5 L/ha, with another programme around 4–6 weeks after emergence at 0.5–1 L/ha depending on cultivation intensity.

Carrots

Application stages include:

• Intensive root growth
• Root formation

Typical rate: 0.5–1 L/ha.

Strawberries

Applications are shown around:

• Pink bud
• Petal fall

Typical rate: 0.5 L/ha.

Cabbage

Applications include:

• 4–6 leaf stage
• Head formation
• Loose head stage

Rates shown range from approximately 0.5–1 L/ha depending on crop stage.

Mixing Instructions

1. Half-fill the spray tank with clean water.
2. Add the required amount of Cropmax.
3. Continue filling the tank while agitating.
4. Maintain agitation during spraying.
5. Ensure good spray coverage of the crop.

Cropmax may be used alone or together with compatible pesticides and foliar fertilizer solutions. The manufacturer recommends carrying out a small compatibility test before preparing a full tank mixture.

Application Precautions

• Avoid application at low temperatures.
• During very hot weather, spray preferably in the morning or evening.
• Avoid spraying severely stressed crops during the hottest part of the day.
• Carry out a compatibility test before combining with unfamiliar products.
• Follow crop-specific recommendations and good agricultural practice.

The manufacturer's brochure specifies a minimum storage temperature of 0°C.

Suitable Crops

Cropmax can be used across a wide range of crops including:

Maize • Wheat • Barley • Other cereals • Sunflower • Soybean • Canola/Rapeseed • Potatoes • Tomatoes • Onions • Carrots • Cabbage • Cucumbers • Peas • Strawberries • Grapes • Fruit trees • Vegetables • Flowers and ornamental crops

The manufacturer describes its products as suitable for crops grown both in the open field and in greenhouses.
