Substantial additional yield due to treatment against nematodes

That the drug 'Vydate 10G' is the most effective means of combating nematodes was again shown last year by research by research institute HLB. The test field was located on a plot with high nematode pressure, near Sellingen. On this plot, both the row treatment with 10 kilos of Vydate 10G per hectare and the full-field treatment with 20 kilos of Vydate 10G per hectare showed significant additional yields.

Corteva agriscience have had these kinds of tests carried out for years and every year comes Vydate 10G, compared to the alternative granulate, came out on top. This time the returns were 51% and 92% respectively, where the alternative product was stuck at a 13% return. This was mainly due to the dry conditions.

Even with the dry conditions of last year, Vydate 10G (due to good solubility and systemic effect) offers a reliable solution against nematodes. Due to this systemic effect, Vydate 10G also has an effect against aphids and the first generation of Colorado beetles. The granulate can be used in all weather conditions on all types of soil, including the cultivation of potatoes, onions, beets, carrots and bulbs.

In line or full field treatment 
Whether it is best to opt for row treatment (10 kilos per hectare) or full-field treatment (20 kilos per hectare) strongly depends on the situation on the plot. Which nematodes are there, and how many are there? A soil sample can clarify this. In addition, factors such as pH, soil organic matter content and variety choice influence the correct dosage of Vydate 10G. Your advisor can advise you on this.

Some situations in which a full-field treatment with 20 kilos of Vydate 10G should definitely be considered:

• Are you dealing with more virulent populations, which also cause damage to resistant potato varieties? It is then important that the multiplication of nematodes is prevented. The longer duration of action of a full-field dose of 20 kilos has clear advantages here.
• When infested by the root knot nematode (the Meloidogyne chitwoodi) we see virtually nothing above ground. But, underground, the consequences are all the more visible. In case of heavy infestation, the potatoes look like oliebollen and are no longer suitable for consumption. In these cases, a full-field dose of 20 kilos gives a much higher percentage of tubers that are free of infection.
• There are more and more plots where several types of nematodes occur at the same time. With this type of mixed contamination, a full-field dose (20 kilos) quickly gives a much better financial result.

Use the crop protection products safely and read the label and product information before use. For more information about the treatment of nematodes, visit www.aaltjes.net.
