Slugs and sowbugs may also pose problems. Diseases such as downy mildew and rots brought on by hot, wet weather are also problems. Floating rowcovers made of spunbonded polypropylene can be used to exclude insect pests. The fabric comes in varying weights. Heavier types can be used to retain heat for frost protection while the lightest can be used into the summer to exclude insects.
