Weed control in extensive agriculture

Control de malas hierbas en agricultura

Weed control in extensive agriculture results in an essential task to ensure a better crop yield. World cereal production in 2016 is 2.600 million tonnes. The latest FAO report forecasts that production will exceed 7.9 million tonnes (+ 0.3%) as predicted in February. Figures for the 2016/17 season exceed the record production obtained in 2014/2015 by more than one point, according to the International Grains Council.

In Spain, data from the Ministry of Agriculture, Fishing, Food and Environment indicate that an average of 6 million hectares of cereals are grown. This is the sector with greater territorial base and with a distribution throughout the whole territory. The Ministry considers that 42.8% of production is barley while 30.1% corresponds to soft wheat.

Because of its role in diet and food production, cereal farming is a key element on the board of the world economy. Due to its increasing importance, it is necessary to produce instruments for weed control in extensive agriculture, given its immediate impact on crop production and yield levels.

Seipasa a company specialized in natural solutions for agriculture with zero residues, has developed tools to guarantee weed control in extensive agriculture. Kynetic4 is a biostimulant produced to maximize the action of herbicides. It is based on the action of physiological intermediates and amino acids of plant origin. Being added to a herbicide program, Kynetic4 enhances absorption, taking action as a synergist and activator of herbicides, fungicides and foliar fertilizers.

Kynetic4’s ability to activate plant’s physiological processes not only results in increasing vegetative development but it also makes an improvement of the final production in extensive crops and cereals.

Reduction of stress caused by herbicides

Kynetic4 also reduces stress caused by herbicides. When herbicides are applied, crops are subjected to abiotic stress. The plant suffers from metabolic wear and requires an extraordinary energy supply to recover. Kynetic4 acts as a supplement to overcome episodes of higher stress.

An example of how Kynetic4 performs is observed in the trial conducted in Blairville (France). It was based on the efficacy of the product within a herbicide program. The results obtained revealed that the efficacy of Kynetic4 together with a herbicide program was 94.5%, compared to 90.4% of a herbicide program without any enhancer being applied. Other weed control programs were also measured, but lower efficacies were observed.

Yield increase with each of the treatments was also evaluated in this trial. As shown in figure 1, the best results were obtained when Kynetic4 was applied.

Weed control in sugar beet farming

Applying Kynetic4 together with herbicides in sugar beet farming allows to obtain higher efficacies in weed control in extensive agriculture. Global production of sugar beet in the 2016/17 season is forecasted at 171 million tonnes, according to International Sugar Organization Brazil, India and the EU are the main producers. The importance of this crop requires the implementation of tools ensuring optimum performance.

Seipasa researched on the supply of Kynetic4 together with a herbicide program on sugar beet farming. The test, conducted in Belgium (Faimes), aimed to assess the benefits of a normal program of herbicide treatments together with Seipasa’s biostimulants. The purpose was to enhance the herbicide effect at the time the crop received biostimulation in its growth. The test was also applied to reduce the stress effect caused by chemical elements.

Four post-emergence applications of the usual herbicide program used in the region were carried out. The active ingredients of the 3 products were ethofumesate + fenmedifam + desmedipham; metamitron and clomazone.

Also, 3 products were included to evaluate compared effectiveness not only on weed control but also on the effects they could produce in the crop. Two additional evaluations were performed during the time elapsed between applications. An addition, a third evaluation was conducted 27 days after the last application of the 3 herbicide programs.

Kynetic4 shows similar performance compared to the reference product, but better than using animal amino acids. Efficacy of the combined use can be observed in figure 2. Kynetic4 in sugar beet cultivation improves the assimilation of treatments and stimulates the development of the crop, producing better and higher yields.
