Nematodes, their are so many species of nematodes it is mind boggling, however today we’re focusing on one classification of nematode, the parasitic type. In high enough quantities plant-parasitic nematodes can cause turf to turn yellow and die off, this can create an issue as it is not ever apparent that the cause of such damage is nearly invisible pests, many turf managers assume it is some form of disease or other pest and so never use the correct methods to remove the problem.
To control nematodes is fairly simple in relation to discovering that you have a nematode issue in the first place as they are a sneaky bunch and difficult to pin down, however once you have dicovered the infestation it is almost as simple as applying a nematicide and erradicating the problem from there. However nematodes dwell beneath the soil and so special methods are needed to apply the nematicide, such as cutting grooves in the turf to allow the nematicide to sink in to mazimize efficacy.
This actually kind of disgusts me, I mean, think about it, hundreds of thousands of hidden worms wriggling beneath the surface, devouring the turf from the bottom up, a silent killer who may not be discovered in time if at all, the damage it causes looks like a great many other types of damage and this is what makes it so effective in its purpose.
