Copeo® Seed Treatment
Copeo seed treatment is a new seed treatment for cotton that contributes to higher yields under nematode pressure, bringing a new mode of action to the cottonseed treatment market. Available on Stoneville® Cotton and FiberMax® Cotton varieties.
Copeo seed treatment delivers additional yield potential to both susceptible and nematode-tolerant seed varieties, making it a good fit for any nematode management program.
Yield loss to nematodes is more than double the estimated yield loss to seedling diseases, such as Rhizoctonia, Pythium and Thielaviopsis.
The Nematode Problem
While nematodes may be too small to see, they’re causing problems too large to ignore. Losses are staggering. The Society of Nematologists estimates that plant parasitic nematodes cause more than $3 billion worth of crop losses annually.
Perhaps the most troubling aspect of the nematode issue is that the symptoms of nematode attacks either can’t be seen or are often credited to other problems. Because the symptoms are common to a number of crop stresses, it is sometimes difficult to distinguish nematode damage from insect or herbicide injury, nutritional deficiencies or soil problems. All soil types – not just sandy soils – can have significant infestations of plant-parasitic nematodes.
Symptoms in cotton can include:
The question should never be whether to test, but when to test.
Populations grow throughout the season. University nematologists generally recommend sampling for cotton nematodes in the summer or late fall.
Soil sampling is the best way to determine which species of nematodes are in your fields and at what levels. Check with your state’s land-grant university or Extension agent to find out where to send samples.
Nematodes are parasitic, and their life cycle is fairly common across types. Although nematodes progress through the stages of egg, juveniles, and adult, it is the juvenile stages that represent a threat. Here’s how they cause damage to your plants.
Some nematode species can produce six generations in a single year.
