Pesticide Use Policy
It is our goal, through Integrated Pest Management, to produce
the highest quality seedlings possible without the use of
pesticides and without compromising the requirements of
our clients for seedlings which have the best survival and performance potential.
We use the following approaches in working towards our goal:
- Cleaning and disinfecting the greenhouses and growing containers
after use to reduce the carryover and buildup of any pest population.
- Providing a sufficient oversow of seedlings to provide a tolerance
level of pest damage before considering the use of natural or synthetic controls.
- Understanding the life cycle of each pest, the environmental conditions
which encourage pest development, and the appropriate
timing for effective control with minimum treatment.
- Balancing the growth required to achieve contractual specifications
with the development of resistance to disease, where conflicts exist.
- Maintaining environmental conditions which discourage the development
of pests, to the extent that environmental conditions can be controlled.
- Maintaining a relatively stress free growing environment where possible,
and providing progressive conditioning during changes
in growth patterns to reduce the susceptibility of the seedlings to pests.
- Keeping the number of weeds in the crop and around the nursery
to a minimum to reduce the number of areas where pests can overwinter or hide.
- Monitoring accumulated heat units to better predict the emergence of insect pests.
- Maintaining a scouting program which monitors for, and identifies,
the level of any specific pest population prior to considering
the use of any natural or synthetic controls.
- Regularly removing unhealthy seedlings to reduce the number of susceptible
seedlings on which pests can feed or develop.
- Using biological controls, such as predator insects and/or other
organisms, where these have been proven to be effective,
where a low human hazard has been established, and where
the conditions for use are suitable for effective control of the pest.
- Providing appropriate environmental conditions and stock handling
procedures in cold storage to prevent the development of disease.
Where the use of pesticides becomes necessary, we use the following approaches:
- Using pesticide baits wherever possible to avoid treating seedlings with pesticide.
- Using the least hazardous effective pesticide available, particularly
to humans, but also considering all non-target organisms.
- Alternating the use of pesticides to reduce the risk of developing
resistance in any specific pest to any one pesticide,
which could result in the need to use increasing concentrations
of pesticide to achieve effective control.
Integrated Pest Management
From the Nursery Crop Production Guide, produced by the Province
of British Columbia, Ministry of Agriculture, Fisheries and Food
Integrated pest management is a decision-making process that uses all
necessary techniques to suppress pests effectively, economically,
and in an environmentally sound manner. The elements of integrated pest management include:
- Planning and managing ecosystems to prevent organisms from becoming pests.
- Identifying potential pest organisms.
- Monitoring populations of pests and beneficial organisms, pest damage, and environmental conditions.
- Using injury thresholds in making treatment decisions.
- Reducing pest populations to acceptable levels using strategies
that may include a combination of biological, cultural,
mechanical, behavioral and, where necessary, chemical controls.
- Evaluating the effects and efficacy of pest management practices.
