Roughage tour Corn - Week 30
Quality improvement in maize
The corn growing season is progressing. During this period, fungal disease and leaf and eye spot disease can appear. Propulse can be sprayed for this. Read here how participants of the Roughage Tour apply this and what vision they have about this.
In the past period, the conditions for the development of the various fungi have been good. Moisture and moderate temperatures allow the fungi to infect the corn. This is very different from recent years when it was very dry. Therefore, check your plot.
Bayer has marketed the product Propulse to combat this. Spraying can be done where necessary. Make sure that the boom of the sprayer can reach sufficiently high (just over or above it through the crop). Also pay attention to the firmness of the crop. Due to the rain and rapid growth, some plots may be prone to stem breakage. Then postpone the spraying for a while.
Spray from visible panicle (BBCH 53) to the end of flowering (BBCH 69) with 1,0 ltr/ha Propulse. During the Roughage Tour, Bayer has set up a trial for the operation of Propulse with three participants. Below is the vision and experience of the participants.
Curious about addition
At Roel Assies in Zeewolde (Flevoland), the contractor sprayed 23 hectares of maize with Propulse on Saturday 5 July. Due to the large rotation of 1 in 8 which Assies manages to achieve on the acreage, the disease pressure is not very high. Still, Assies is curious about what addition Propulse has to the maize crop and whether it will possibly yield extra yields. Assies indicates that the corn crop takes minimal damage when the sprayer drives through it.
Damage minimal
Propulse was also sprayed at Joost van Nostrum in Sint-Oedenrode (North Brabant). The main reason that Van Nostrum is participating in the trial is out of interest and possible improvements for maize cultivation. Van Nostrum indicates that during the spraying work, the maize bends under the sprayer, but it has recovered after two days and the damage is therefore minimal.
Plus maize cultivation
Jan Henk Waterink from Beerzerveld (Overijssel) is taking part in the trial and has Propulse sprayed into the maize crop. Waterink made a conscious decision because due to wind damage in the maize, there is a kink at the bottom of the plant, causing the crop to grow together. As a result, the leaf disease pressure is higher. In the past, Waterink has sprayed with other agents against leaf disease. Waterink is familiar with the product because he has also used it in the cultivation of beets and potatoes. "Perhaps it will also give a plus for maize cultivation in the future," says Waterink.
