Its a percentage thing. No way to stop mother nature, but to retard, delay and influence negatively the onset of pathogens like these nematodes to allow the fruit production period to occur in a healthy way before a delayed nature catches up with it all is about all I can muster. This was the singlemost productive garden I have had in years. I started tilling in the winter, and used a thyme oil humic acid product that was effective in suppresion but obviously not eradication. In fairness, after the plants had given the vast majority of their production I quit spraying and no doubt that lack of spraying allowed advance of the nema. But many plants showed no effect. These were the worst that I found.
My wife was bitching because we had too many tomatoes, okra and so forth. Prior gardens had losses so that a ratio of production became a norm. I changed the suppression in the soil, produced more, and was secretly pleased to hear her complain about having too much. I am weird that way though.
The observation is that at the end, the nema is still there. But I got the fruit first.
Don't think a trip with you, @Upsy Daisy , to feast upon his cookies and his beloved Becky's art works will improve my lack of intellect! But the prospect of driving up your infinite impressive drive way will certainly fuel my desire to join the capitalist brigade, @DirtMechanic !
Now, what else can I sell in my garden to pay for a bag of horticultural grit???
