A crop is a cultivated plant that is harvested for consumption.
Crops are subject to seasonal conditions and infestations.
The player will be warned of any crop field infestations with an infestation icon as shown to the right.
It is important to note that crop fields can become infested, this will destroy the entire crop. It also means that if the same crop is planted in the same area again they will have a much greater chance of being infected, as such it is recommended to plant a new type of crop in the field next year. Also of note is that if you have multiple crops of the same type in fields close together the infestation can spread, be sure to separate crops of the same type to avoid this problem.
The best course of action during infestation is to order your workers to harvest the crop as soon as possible, this ensures you save some of the drop that was already produced.
