When one living organism is used to inhibit the activity of a living plant pathogen, it is said to be a biological control agent (BCA).
Prewash tools, benches, and equipment to remove soil and plant debris because disinfestants do not penetrate these well.
Root rots of floricultural and woody ornamental crops are one of the most important causes of crop loss.
A fungicide disrupts either energy producing reactions or a chemical building (synthesis) reaction within the target fungus. The way it kills the fungus is termed the fungicide's 'mode of action.'
The following is a guide to assessing the threat of disease in a nursery operation.
The following is a guide to assessing the various procedures and equipment used in a greenhouse, keeping in mind the threat of pathogen, mite, and insect population development in the crops being grown in a particular greenhouse.
The objective of heat treatment of soil is to reduce the numbers of weeds, insects, and disease-causing organisms in the soil and thereby promote plant vigor, increase yield and quality and decrease the need to use pesticides later in the production cycle.
‘Organic’ methods involve growing and maintaining healthy plants without using synthetic (man-made) fertilizers, pesticides, hormones, and other materials. In organic disease control, natural materials (things found in nature or that exist in the environment) can be used to inhibit or prevent the activity of plant pathogens.
Wettable powder pesticide labels list the amount to use in terms of pounds per 100 gallons. When lesser amounts are to be mixed, growers, homeowners, and even university personnel frequently follow the old rule of thumb that 1 lb/100 gal = 1 tablespoon/gal.
