Use these techniques to suppress pest populations.

Check Table 8-21. Products Used on Strawberries, on page 180

**Page numbers refer to pages in Publication 360 - Fruit Production Recommendations**

Table 8-21. Products Used on Strawberries

Use this table as a guide, but refer to product label for specific information.

The preharvest interval is the number of days between the last spray and first harvest.

The re-entry period is the minimum interval that must be observed between applying the pesticide and working in the treated crop without protective equipment. If no re-entry period is stated on the label, assume that the spray solution must be dry before re-entry can occur.

The maximum number of applications is the labelled maximum number for the growing season, and may be higher than what is recommended for resistance management or for preserving beneficial insects.

Table 8-22. Miticides Registered on Strawberries


Miticide	Stage site of mite controlled	Comments	For use before harvest	For use after harvest
Apollo SC	Eggs, very young nymphs	Should be applied when most mites are in the egg stage. This miticide works best if applied early in the season, when generations tend to be most synchronous.	Y	N
Kelthane 50 W	Nymphs	An older product. Resistance to Kelthane has developed where it has been used repetedly. This miticide works slowly; do not expect rapid knockdown of mites.	Y	Y
Agri-Mek 1.9% EC	Adults, Nymphs	Translaminar (locally systemic). Absorbed best by new, expanding leaves.	N	Y
Pyramite	Adults, Nymphs	A contact miticide providing rapid knockdown of adults and nymphs.	Y	Y

Y- Allowed usage
N- Cannot be used

Table 8-23. Effect of Fungicides on Strawberry Diseases

Ratings in Bold indicate the disease is listed on the product label for control or suppression. Please see the product label or crop calendars for registered uses. Use fungicides only for diseases listed on the product label for the crop and for the disease. Additional Information is provided in this table to assist the grower in choosing the best fungicide for control of diseases listed on the product label.

* Use fungicides only for control of diseases listed on the product label.
0 = no control;
+ poor to fair control;
++ = good control, some limitations;
+++ = excellent control, few if any limitations
R- pathogen resistence (insensitivity) to the fungicide has occurred in some locations
P- may be phytotoxic
?- suspected level of control, needs confirmation
