And in the absence of their natural enemies, the remaining plant-parasitic eelworms proliferate much faster.
Another disadvantage of the chemical option is the cost of the chemicals. But by planting a cash crop instead of the trap crop, the farmer can earn money and balance out the cost of the chemicals.
