Plant Health<br />
Walters Gardens has made a strong commitment to provide only the<br />
most healthy, vigorous product to our customers. All of our crops are<br />
tested regularly for the most common viruses as well as additional<br />
genus-specific viruses where needed. Our fields and greenhouses are<br />
also regularly scouted for signs of pests or diseases. In addition to the<br />
dedicated efforts of our Growers and Plant Health Team, we make an<br />
effort company-wide to maintain clean and preventative practices to<br />
limit the spread and introduction of pests, diseases, and viruses.<br />
How to Identify<br />
Virus-Indexed Plants (VIP)<br />
A virus-indexed variety is one that has been tested and deemed<br />
free of the viruses listed (right) up to the point of testing. A bow<br />
tie symbol is located in the key code of each variety that has<br />
been virus-indexed.<br />
Sustainable Production Practice<br />
and Integrated Pest Management<br />
In the Fields<br />
Understanding the vital importance of plant health, we remain<br />
vigilant in preventing problems in our fields. Before a crop is planted<br />
in the field, we make sure our planting stock is clean and diseasefree.<br />
We then diversify our plantings so that disease prone items are<br />
never planted in the same place twice. All of the equipment used<br />
to plant and harvest our hosta stock blocks is sanitized between<br />
cultivars. We also scout weekly for weeds, insect damage, unusual<br />
variations in growth, trueness to type, and overall plant health.<br />
In the Greenhouse<br />
Prevention is key when it comes to pest and disease management<br />
in our greenhouses. We do weekly scouting for any pest, disease, or<br />
nutritional issues and do preventative spraying in regular intervals<br />
to prevent the onset of disease. Our goal is to catch problems at the<br />
earliest stage possible and to target the treatment to the specific<br />
crop before it spreads to other plants. When treatment is needed,<br />
we use beneficial insects or reduced-risk pesticides which target<br />
specific pests rather than using broad spectrum chemicals. We have<br />
not used neonicotinoid containing products on our production crops<br />
since 2014.<br />
Virus Prevention and Index<br />
We take great pride in the attentiveness of our Plant Health and<br />
Greenhouse staff when it comes to identifying and preventing viruses<br />
in our plants. All of our plants are tested on a regular basis regardless<br />
of appearance or history. Because there is always risk of a crop being<br />
exposed to a virus, and more so in a field environment, we will not<br />
give VIP status to a variety if we feel there is too much risk of infection<br />
between testing and shipping. If a variety is prone to viral infection,<br />
extra steps are taken to ensure that our stock and production lines<br />
always start with clean material.<br />
