Do you need a natural product to relieve the effects of plant stress during critical periods of growth? Maxicrop is widely used by organic fruit, vegetable and salad crop producers. It helps resist problems due to pest and disease attack. It also minimises environmental stresses.

Help early on

Early on in the growth of a crop, Maxicrop helps stimulate soil microbial activity. It turns over any plant residues and makes nutrients more readily available. It could also reduce nematode damage. This in turn encourages healthier rooting and better crop establishment. There are minimal checks in growth or transplant shock.

Increases growth and disease resistance

During the season, little and often applications, will maintain high leaf chlorophyll levels. This makes the most of available radiation, promoting strong growth. Regular applications will also maintain a high stress-resistance threshold. By doing this, you will help the plant’s internal defence mechanism keep pests and diseases at bay

End of season boost

Towards the end of the season, Maxicrop helps retain green leaf retention and productive growth. It maximises yield potentials and improving crop quality.

Two base liquid products ““ Maxicrop Concentrate and Maxicrop Original – are available. Both are approved for organic growing systems by the Soil Association and have been widely used for years.
