5.9.3.2 Weed Control

5.9.3.2 Weed Control

In Puelche a weed control plan was developed, determined by the rotation of chamomile crops.

FIGURE 5.9.1 Handpicking with a special comb.

The rotation considers an intermediate cleaning crop once a year, using oats sown in December-January every year. These seed are sown over the stubble formed by the chamomile that has been immediately incorporated after the harvest.

This rotation of crops allows a weed control; the main species are:

Convolvulus arvensis L.

Polygonum persicaria L.

Veronica persica Poiret

Raphanus raphanistrum L.

Capsella bursa-pastoris (L.) Medikus

Galega officinalis L.

Spergula arvensis L.

Plantago lanceolata L.

Echium vulgare L.

Silene galica L.

Leucanthemum vulgare Lam.

Anthemis cotula L.

Chenopodium album L.

Taraxacum officinale G. Weber ex Wigg.
