looking for an active biological control product (bacteria and fungi) of root-knot nematode in tomato and cucumber fields under Iraq weather conditions (hot summer).
Your best approach would be to trial the potential candidates under your conditions in Iraq with your target crops.
You may want to create a sick plots in a sandy conducive area where you can grow the infested crops to create a uniform infestation.
With a sick plot have non infested controls and then apply your treatments under real life condition. I would suggest you have over a dozen treatments that are applied as directed for commercial formulas.
Include at least 3 replications for each treatment and have adequate replicate size and use border rows.
Thanks all for your advice, but I need to try some commercial products that you recommend through your work or experience among the a lot of products in the market.
