Barriers serve to exclude pests from the crop and include the use of ‘cutworm collars’ placed around the stem collar of young transplants to prevent cutworm damage. Other barri- ers include row covers made of transparent or translucent materials such as mesh that allows light and air to enter, but blocks insects. Typically, row covers are supported above the plants with hoop frames
Field pests. Damage from field insects is not generally a major factor for oat crops, however there is a zero tolerance to insects in export hay.
Pest management . Control of aphids is the main approach to the control of plant virus diseases. Rapid action is often needed to avoid the establishment and spread of virus disease in a crop. Monitoring. Plants should be visually inspected for the signs of aphid infestation.

Aphids are small insect pests with oval-shaped green, brown or black bodies. Often occurring in colonies, aphids suck on sap, causing loss of vigour, and in some cases yellowing, stunting or distortion of plant parts.
Beneficials may not arrive in crop early enough to prevent the build up of aphid numbers to above threshold levels, but can be important in suppressing population build-up following control, and are effective against low to moderate infestations.
temporary systems, such as in annual crops, could be unfavorable for this equilibrium. Once this balance is broken, phytophagous insects and mites tend to reach high population densities, causing losses to the farmers.
Order Hemipitera; Family Aphididae. Pest description and damage Several species of aphids may feed on the foliage stem, flower, bud, bark or root tissues of conifer and deciduous trees, shrubs as well as other plants in landscapes.
