Description

CYD-X® contains an insecticidal baculoviruis (Cydia pomonella granulovirus) that is specific to larvae of the codling moth (Cydia pomonella). Because of this specificity to the codling moth, CYD-X® provides a unique opportunity for biological control of codling moth with NO harmful effects on humans, domestic animals, wildlife, beneficial insects and plants.

Mode of Action: CYD-X® is a biological insecticide, which must be ingested by larvae in order to be effective. Upon ingestion, the viral occlusion bodies (OBs) dissolve in the larval midgut and release infectious virions. These enter the cells lining the digestive tract and replicate in the nuclei of those cells. The resulting progeny virus infect other tissues within the larva, which stops feeding and eventually dies from massive viral infection. After death, the larva disintegrates, releasing billions of new OBs, which may infect other codling moth larvae upon ingestion. Death occurs 3 to 7 days after ingestion of CYD-X®, depending on dosage and ambient temperature. Death may occur more quickly at higher temperatures and higher dosage.

Use Instructions

See product use instructions for complete information. CYD-X® must be mixed with water and applied as a spray to fruit and foliage.

Use non-chlorinated water at a pH near 7.0 in the spray-tank mix. Mix 1 tsp of CYD-X® per 5 gallons of water and apply directly to each tree using a hand pump sprayer or other suitable spray equipment. Spray just enough to wet all leaves and fruit with minimal run-off or dripping. Total coverage depends on the size of trees to be sprayed and the type of sprayer used.

Apply CYD-X® first in late spring or early summer, when eggs of the first generation of codling moth begin to hatch. For maximum effectiveness, apply CYD-X® at least twice during each larval generation. When pest pressure persists, additional applications may be necessary in mid- to late summer. Consult your local Cooperative Extension Service for more information about the best timing of codling moth sprays.

For best results, CYD-X®should be refrigerated when not in use and should last at least a year. Non refrigerated product should be used within 3 months. Bioactivity of the virus can be degraded by exposure to high temperatures ( > 90°F) for long periods. Always store CYD-X® in its original bottle in a cool, dry place, out of direct sunlight. Shake well before use. CYD-X® can also be frozen for extended storage without harm.

Time consuming application but it works

At our property in Forestville, CA we have two standard pears, three standard apples, two semi-dwarf apples and one multi-graft Asian pear tree. After years of frustration with codling months, I tried this product in 2016.

I followed application recommendations from the UCIPM website (University of California Integrated Pest Management). I began applications using the degree day calculator from the local UC Extension website. I applied Cyd-X every 7 to 10 days with a good pump sprayer. You will want one that can produce a fine spray without clogging. I found that a nozzle with a fan spray worked well on the standard size trees. I used 10 to 12 gallons of mixed product per week and it took about 2 to 3 hours to spray all the trees because I had to use an orchard ladder to spray the tops of the standard trees. Spraying will be much easier if you keep your trees pruned to about 8 feet.

I mixed Cyd-X with distilled water and 1% horticultural oil (all seasons oil) per the UC recommendations. Results were very good with only about ten percent of the fruit being damaged by codling moth.

As with any aerosol application, I wore goggles, mask and protective clothing and posted notices on my fence regarding the spraying so that neighbors would not be alarmed by my "hazmat" garb.

Expensive and time-consuming, but I think it works

In our San Jose, California yard we have two half-size apple trees and one standard pear tree. So, think of it as two trees. It takes one gallon of spray mixture to cover them.

For the past five years, I sprayed them once a week, mixing several drops of Cyd-X mixed into a gallon of chlorinated tap water. I stored my Cyd-X in the freezer from September thru April. I was never sure whether this had any effect or whether I was wasting my time. I had codling moths in maybe 30% of the fruit.

This year, starting in I think the middle of May, I started a new bottle of Cyd-X and see that now the instructions say to use distilled water, and maybe a stronger mixture. So I used filtered rainwater (fortunately we got some rain in May) and, when that ran out, distilled water from the supermarket. And I sprayed *twice* a week.

Results were definitely better. Codling moths were in maybe 10% of the early fruit, maybe went up to 20%, and then back down to maybe below 10%. The fact that it went down is encouraging for Cyd-X because, given what I did, I would expect mostly the later generations of codling moths to have been knocked out. And, usually, codling moth damage increases as the summer progresses.

Back in May, I think, I sent a message to the manufacturer asking for their opinion on my regimen but never got a response :(. I think that commercial growers economize by spraying only during the generational peaks, which occur every few weeks. But I don't have the time to research that, with the many microclimates in the average California yard, data from the "county extension" service is going to be useless, as are monitoring traps because last year had traps they only collect a few codling moths during the entire year. In other words, I have no practical way to determine when the peaks are.

Analysis: If eradicating codling moths is your hobby, I recommend this product, and the spraying regimen I used. But the cost is quite high. Adding in the sales tax and 5 gallons of distilled water, the cost for me was $30 per tree per year, plus 40 minutes per week for 12 weeks including the time it takes to fuss with clogged nozzles and cleaning out the sprayer once in a while. If you're growing pears and apples to "save money", you're probably better off cutting down the trees and buying your fruit at the market.

If someone can get recommendations out of the manufacturer for home gardeners, please post them!
