Brassica

When cultivating brassicas you like to start with compact, sturdy and resilient planting materials, to ensure smooth and easy initial growth. Your plant breeder is faced with the challenge of providing perfect quality seedlings. He is also the first in line when it comes to building resilience in young plants. After that, it’s down to you. We have a number of solutions that are easy to use to make plants robust and resilient and to keep them that way. This applies to the seedlings and plants that are a lot further along in the growing process. 

Start your brassica cultivation with strong plants!

Strengthening resilience therefore preferably starts with the plant breeder. A plant grown to be more robust and resilient from a young age, but also more compact, stronger and sturdier will produce top-quality brassicas later on. To help the young brassica plant to grow healthily, we recommend using our CE marked fertiliser ArgicinPlus. This product contains three different components: orthosilicic acid (silicon), willow bark extract and colloidal silver. 

The silicon built into the cell walls of the stalk and leaf literally strengthens these. Water and nutrients also reach their destination as silicon improves the internal transport of moisture.

Finally, the willow bark extract in ArgicinPlus plays an important role in root development. The young brassica plant grows better and more evenly and absorbs water and nutrients more readily.

The use of ArgicinPlus, possibly supplemented by SilicaPower for additional silicon, produces more stocky, compact and sturdy seedlings with short internodes and more leaves. These seedlings are less likely to blow out of the ground after being planted out. Therefore, as a grower consult with your plant breeder about strengthening the seedlings in order to give your commercial growing a (lasting) head start.

Recommended dosage/advice for use ArgicinPlus in the cultivation of brassica plants

  • Recommended dosage: 1.0 litres/ha/time of ArgicinPlus with spray mixture quantities of up to 500 litres. For every additional 100 litres of spray mixture, add 0.2 litres of ArgicinPlus. Crop spraying is preferable. Administration by LVM or irrigation is an alternative.
  • Interval: Every 7 days from the time at which the seed leaves have unfolded. Spray a total of 6 to 7 times, depending when these were sown. 
  • If a decision is made to spray additional silicon in the form of SilicaPower, the recommended dosage for this is 0.5 litres/ha/time. 

 

When ArgicinPlus is used, the following applies: residue-free, no growth inhibition, no re-entry restrictions and no safety term.

Research by Vertify: brassica plants are more resilient following the administration of SilicaPower and Cuprum

SilicaPower and Cuprum are used successfully in the commercial growing of brassica plants, such as broccoli. Research by Vertify has demonstrated that both products make plants more resilient. 

Left: untreated. Right: treated with SilicaPower and Cuprum

SilicaPower ensures a lasting, stronger crop throughout the growing season

SilicaPower is a very pure formulation of silicon that dissolves readily in water. It strengthens the cell walls and the epidermis of the leaf and ensures well-balanced absorption and distribution of calcium, magnesium, manganese and boron throughout the plant. We recommend using SilicaPower during commercial growing for an optimum result. Seedlings, brassicas and broccoli heads that have built more silicon into their cell walls, are stronger, less susceptible to stressful situations and diseases and less attractive to pests. The harvested product is stronger and more suitable for long-term storage.

Recommended dosage/advice for use - SilicaPower in brassicas

  • Recommended dosage: 0.5 litres/ha/time of SilicaPower. SilicaPower can be mixed with a different spray and, with its extremely low EC of 0.02 mS,  does not raise the EC of the spray mixture.
  • Time: the first spraying takes place 3 weeks after planting. If the resilience of the seedlings was not boosted at the plant breeder, start a week earlier. The application interval is 10 days. Maximum 5-7 treatments, depending on the duration of cultivation. 

 

More robust broccoli with Cuprum

Suboptimal growing conditions with, for example, an excess of moisture, can cause considerable problems in a crop like broccoli. Head rot is a major cause of this at that time. Resilient, robust plants are less likely to suffer from problems. We therefore recommend administering Cuprum to maintain resilience during the final stage of broccoli growth. Cuprum is a fertiliser with CE marking that contains micro-copper which is required by the plant to produce certain proteins that help it to maintain its vitality during non-optimal growing conditions. By opting for Cuprum instead of a different copper foliar fertiliser, the amount of copper used is minimal. A responsible choice in terms of its impact on soil life and groundwater.

Recommended dosage/advice for use Cuprum in broccoli

  • Recommended dosage: 1 litre/ha/time per treatment.
  • Time: initial spraying is just before the head closes. Then every 7 days, a maximum of 2 sprays.

Increase the resilience of young brasicca plants

Strong, compact and vital brasicca seedlings are less likely to blow out of the ground after being planted out and grow into healthy brasicca plants that remain vital. Including in suboptimal growing condtiions.
