The Problem With Monocultures The problem with monocultures, Wetzel said, is that if an insect likes the crop, that insect has a large food supply to draw from all in one place. Conversely, a field containing a variety of plants does not offer a large block of food for the insect, so it will not get the nutrients it needs to survive and thrive.

Poor soil, tree crowding, weed control, irrigation, zinc foliar sprays, nitrogen fertilization, insect control and disease prevention become very important during high crop years such as 1993 and 1995.hen pecan problems occur the cause is frequently not easy to identify. However, once the problem or group of problems is identified, the grower can go about correcting the problem. If the problem cannot be solved, the grower at least knows what to expect and has the option of abandoning or destroying the trees.
