Post-emergence herbicides on cereal crops: treatments to boost their effectiveness and help overcome crop stress

Keys to the use of post-emergence herbicides on cereal crops

The use of post-emergence herbicides on cereals features prominently on the list of treatments applied to these crops. During the winter season cereals initiate the tillering phase. At this stage early weed control has a significant effect on subsequent crop development.

Eliminating weeds is necessary to prevent reductions in crop yields that leads to profit loss. Consequently, it is important to apply suitable solutions to ensure the maximum efficacy of herbicide treatments during post-emergence, but it is equally important to use the tools available to help crops overcome the stress experienced after applying herbicides.

Although the species of weeds differ from one zone to another there are certain varieties of grasses that are widespread throughout Spain. Amongst these is “wild oat” (Avena sterilis, A. fatua), that appears between October and April; ‘ryegrass’ (Lolium rigidum), which germinates with the onset of early autumn rains and begins to emerge before cereal sowing; or “ripgut  brome” (Bromus rigidus, B. diandrus), which also begins emergence with the first rains of the autumn season. 

In these and in other cases using post-emergence herbicides on cereal crops is essential to control and get rid of weeds. Herbicides are not always applied alone but rather in combination with other solutions. Foliplant is a Seipasa product that is specifically recommended for this phenological stage in cereal growing.

The key to the benefits that Foliplant provides lies in its formula and in the balance of its complexed elements. The product formula affords a high degree of efficiency when it is applied as it reduces surface tension, which improves its wetting and adherence effect and reduces drift.  All of this increases the absorption capacity of Foliplant via the leaves, making it easier for the active substances to enter weeds when post-emergence herbicides are applied. 

Post-emergence herbicides: overcoming stress

In addition, Foliplant’s formula has a biostimulating effect that helps cereal plants to recover from the stress caused by applying herbicidal treatments. Foliplant provides the amino acids and complexed microelements plants need to overcome these stress levels, and it optimises nutrient absorption, improves photosynthesis processes and favours optimal crop development. 

Its use on cereal crops provides the energy needed to obtain better quality and quantity in final grain production. Foliplant promotes grain-fill hormones and encourages correct photosynthesis activity by providing the key elements for the formation of chlorophyll and carbohydrates. It also helps plants to withstand extreme temperatures and lessens the effects of situations of stress. In addition, Foliplant provides microelements such as zinc which is fundamental for forming auxins that help regulate stem development and elongation, which contributes to the growth of a good, hardy plant structure.

When post-emergence herbicides are applied to cereal crops, early treatment is strongly recommended due to its greater effectiveness. This is also the time to apply solutions such as Foliplant given that, in addition to increasing the efficacy of these herbicidal treatments, it aids  strengthening and optimal plant development.
