Spring with insecticides according to the plant phenophasis

In the protection of plants, the moment in which phytosanitary treatments are applied is as important as the substance used. The application of insecticides based on the phennophase of the plant – that is, the development phases through which it passes – can make the difference between a healthy and compromised culture. A treatment applied too early or too late can be inefficient, even if the product is of quality. In today's article we show you how the phenology of plants influences sketches insecticide And we show you when and how to act for the best results.

What are the phenotofasis of the plants and why does it matter in sketches with insecticides?

The phenotofasis are the phases through which a plant passes in its development: from germination, to dawn, to vegetative growth, to the appearance of gems, flowering, fruit formation, ripening. In agriculture, knowing these phases is essential to synchronize phytosanitary treatments with parasites biology and plants sensitivity.

For example, a parasite like Afida (green lice) mainly attacks plants in the vegetative growth phases. If the insecticide is applied after flowering, when the pressure pressure has decreased or the plant is already influenced, the efficiency of the treatment decreases significantly.

Key moments for the application of insecticides according to Fenophyse:

• Slavery phase and the beginning of vegetative development

This is one of the most sensitive phases. The young plants are vulnerable to the first attacks of soil insects (worms of wire, seedlings, corpsęsnites), but also of those who feed on young leaves.

Recommendation: the application of a systemic insecticide with the action of the soil or through the treatment of seeds is essential to prevent losses at this stage.

• The phase of intense vegetative growth

This is the period in which leaves, stems and branches appear. It is also the period of maximum activities for parasites such as aphids, travel, white muscles or fleas. At this stage, plants need constant protection to maintain their growth rate.

Recommendation: contact or systemic insecticides are applied, depending on the type of parasite and the level of infestation. It is recommended to monitor the traps for targeted application.

This is a sensitive phase, especially from the point of view of pollination. The improper application of insecticides at this stage can affect natural pollinators (bees, bonds), reducing the fertilization of flowers.

Recommendation: avoid applying insecticides during the day. If the treatment is absolutely necessary, apply only to dawn or late evening.

• The phase of fruit and seed formation

Insect attacks can influence the quality and quantity of collection. At this stage, preventive or corrective treatments are applied against parasites that enter the fruit (moths, cockroaches, caterpillars).

Recommendation: Choose insecticides with a short break, so as not to influence human consumption or the rapid sale of the product.

• The phase of maturation and preparation for the collection

At this stage, the application of insecticides is performed only if the risk of loss is high and the harvest is in danger. Any treatment should strictly respect the pause time up to the collection.

Recommendation: avoid unjustified applications. Choose organic treatments or products with minimal residues.

How do you correctly identify the vegetable phenomena to raise insecticides correctly?

It is possible to use agrotechnic calendars or standardized systems such as the BBCH code (useful in viticulture, cultivation of large fruit and crops). In addition, it is essential to consult the technical sheets of the products or local recommendations offered by specialists.

In the end

The application of insecticides on the basis of the phennophase of the plant not only increases the efficiency of the treatments, but also contributes to the reduction of the number of interventions, savings on the costs and protection of the environment. A culture treated over time is a healthy culture. Do you want to make sure to apply the treatments at the optimal moment? Carefully monitor plants and parasites and adapt your phytosanitary plan after the rhythm of nature.
