Oats can outcompete many weeds, as they grow thickly (with many leafy shoots) and vigorously, but are still subject to some [[broadleaf weed]]s. Control can be by herbicides, or by [[integrated pest management]] with measures such as sowing seed that is free of weeds.<ref>{{cite web |title=Oats: weeds and integrated weed management |url=https://www.agric.wa.gov.au/hay-production/oats-weeds-and-integrated-weed-management?nopaging=1 |publisher=Government of Western Australia |access-date=2 May 2024 }}</ref>

Oats are relatively free from diseases. Nonetheless, they suffer from some leaf diseases, such as stem rust ([[Puccinia graminis f. sp. avenae|''Puccinia graminis'' f. sp. ''avenae'']]) and crown rust ([[Puccinia coronata var. avenae|''P. coronata'' var. ''avenae'']]).<ref name="Pratap-2014">{{cite book |last1=Pratap |first1=Aditya |last2=Kumar |first2=Jitendra |title=Alien Gene Transfer in Crop Plants |year=2014 |location=New York City |publisher=[[Springer Science+Business Media]] |volume=2: Achievements and impacts |doi=10.1007/978-1-4614-9572-7 |isbn=978-1-4614-9571-0 |s2cid=26278759 |lccn=2013957869 |oclc=870451823 |page=51 }}</ref> 
Crown rust infection can greatly reduce photosynthesis and overall physiological activities of oat leaves, thereby reducing growth and crop yield.<ref>{{Cite journal |last1=Nazareno |first1=Eric S. |last2=Li |first2=Feng |last3=Smith |first3=Madeleine |last4=Park |first4=Robert F. |last5=Kianian |first5=Shahryar F. |last6=Figueroa |first6=Melania |date=May 2018 |title=''Puccinia coronata'' f. sp.
