On my last business trip to California, I brought back some Ortho, Orthenex systemic insect and disease control concentrate for use in my patch this year to battle aphids, leaf hoppers and powdery mildew.

My question is (not on the label) "when is a good time to incorporate it into my program"? Do I wait until I have aphids or bug issues or do I apply it now and let the systemic value of the product do its work?

Any advice from other growers that have used this product or similar would be appreciated. I buggered up my main plant last year by applying aphid control too strong and too early and do not want the same issue this year.

Thanks/Glenn

Triforine isn't used on vegetables in the US so I have nothing to contribute to how it will perform. It is labeled for use on Cucurbits in other parts of the world often for Powdery Mildew.

Acephate is a solid performing systemic that also has contact properties.

I'd say that if the usual time of day (temperaturte) precautions are exercised this material would do well from late June or early July on.

As with anything new (to you), I'd experiment first on a "back 9" entry....though I'd like to hear from someone who has actually used it on AGs.

I used it first yr i grew but wasent impressed with the results, But i already had pm pretty bad , I now belive after 2nd yr that imunox-pluss is better & still only 15$ bottle & i used it with banner max & had no mildew , the banner is supposed to be growth regulator, but if i had any problem- it was that my main pumpkin grew too fast if anything !!

Be very careful with the acephate...it will fry the leaves if warm or strongly mixed.

I've used orthonex as a systemic control on my pumpkins for three years now, with great success. At the beginning of the year, I use seven to keep insects at bay, but starting in June, as the plant starts running, I use nothing but orthonex on a biweekly basis. I've had cucumber bettles early in the year (June), but never after, even though I have then on other vegetables in other gardens. In late fall, I get some powdery mildew, but very little. When I see it starting, I then start spot applications of a topical antifungal. It also works great on my roses. I'm not sure why more people havn't used it as it's effective, relatively cheap and easy to use.

Wal Mart stores here in the U.S has BAYERADVANCED Tree and Shrub in a big blue bottle. Same thing as Merit just less concentrate. Not to high priced either. I wonder if you guys up North can drive across and find it to take back with you?

The same Merit we use here in the US is also registered in Canada.

Its all good!! After seeing some young aphids on the underside of a few leaves, I mixed up some orthenex and did a test spray on a couple of older leaves. After seeing no ill effects I sprayed the rest of the plant underneath and on top of the leaves.

Not only did in knock down the aphids but it killed a bunch of ants that were farming the aphids for honeydew.

Long and short....this product seems to work great. I will be applying it as recommended and needed, Hope it is as good for PM too!!
