    Organic farming releases as much or more “poisons” than conventional. Just because those poisons “natural” doesn’t mean they are not harmful. Coppersulfate, pyrethrins, spinosad, neem etc are all indesciminate killers. Rotenone is a banned organic pesticide because it’s linked to Parkinson’s.

    The 3/4 number gets a lot worse when you know we really don’t need to farm as much land as we do. If we stopped subsidizing idiotic farming practices and invested heavily in infrastructure, we only need to use 1/4 of the land we do. That includes feeding all the animals. If we migrated to a plant based diet it would be around 1/10th the current land usage.

    GMO are a tool.

    Some GMO’s are a good idea. Virus resistance for example was the first GMO I worked with in the 90’s. Papaya ringspotvirus is an excellent example.

    Some GMO’s were a mediocre idea and an overall failure. Like all the efforts with SAMase for improving shelflife. Aka the GMO tomato.

    Some GMO’s are downright stupid and irresponsible. Like the RR in corn, soy, alfalfa, etc. Its lead to a massive over-application of one chemistry. Creating resistant weeds in all production zones. Or dicamba resistance is soybeans that’s fucking up all the remaining trees, shrubs, and forbs.

    Yeah no. Those are tyvek suits that are used for pesticide application. To complete the outfit they need some nitrile gloves and a fitted respirator.

    For pollen isolation there a whole bunch of different techniques depending on the species. None of them involve getting dressed in one of those uncomfortable monstrosities. I used gel caps when I bred cantaloupes and honeydews (the types used for medications). Slap one over the top of a pollinated flower and it keeps the pollinators away.


  • The grass can be grown with minimal runoff. Unfortunately everyone tries to follow the recommendations of sports fields/golf courses in their yards. All their methods are designed to meet the requirements of the sport, not the needs of the grass.

    Farmers in the Midwest are by far the worse offenders. They frontload their nitrogen application using anhydrous ammonia in the fall or early spring. The ammonia is converted to nitrate by bacterial activity. Part of it then runs off early in the season with snowmelt or rain (that’s when the tile systems are usually draining water from the fields).

    The solution is well known. Use of polymer coated slow release urea at planting or side dressing with straight urea at V4/V5. It’s more expensive per lb apllied but it takes up to 50% less N applied to achieve the same result. Especially compared to fall applied anhydrous ammonia.

    Combined with winter cover cropping nutrient runoff can be significantly mitigated.

    It’s a relatively easy fix but it costs more money… So the pollution keeps running off.

    Brings back a fun memory. On a business trip in France, I was driving and with my coworker (French national).

    I had the GPS set to English pronunciation of the signs etc. My coworker spent most of the two hour drive a complaining about the pronunciation and begging to change the settings. I spent the trip laughing my ass off at him and refusing to change it.

    Pepper seeds begin to mature when the pod turns color. Green peppers are immature peppers and the seeds are not viable. Red or yellow, the seeds may be viable.

    The largest issue with using store bought fruit is the seeds need to be treated with TSP (Trisodium phosphate) when they are harvested. This treatment kills tobacco mosaic virus. TMV and other tobamovisues are common in production areas.

    The plants will also be a segregating F2 plant. So the fruit/plant will look a little different from the parent (F1). Not a big deal in my opinion.





  • ZYMV mainly infects species in the cucurbit family (squash, pumpkin, melons, cucumbers etc). I don’t recall if it bothers tomatoes.

    The only way to know for sure is with an ELISA test strip.

    Of course multiple nutrient deficiencies like Mg, and K can also cause mosaic like symptoms. A heavy infestation of fungus gnats in the soil can also damage the roots and cause similar symptoms.

    So give it some fertilizer and wait a week. If the new growth improves it’s nutrient related. If not, it’s a virus.

    Being a scientist today means you are “smart” in a very narrow and limited area of expertise. Outside of that area, shit goes downhill fast.

    I can’t find the link but scientists and academics are thought to be heavily targeted with affinity fraud schemes because they rarely report when they are duped.

    Two things are going on.

    First the leaves - That is sunscald. It happens to plants that are raised under lower light conditions then exposed to direct sunlight.

    Second the plant is experiencing transplant shock. This is a wound response from the roots being damaged during transplant. The plant has to pause it’s rapid growth to heal it’s roots and grow new ones. This can take a few weeks in severe cases.

    Now for the good news - if the plant is sending out new dark green smaller leaves it’s recovering from the damage and will eventually be fine.


  • The American system for me.

    Halfway through the year cost so far:

    Relatively inexpensive union insurance for the family $2310. Out of pocket expenses so far $3,700. Total $6010 so far…

    Estimated total by the end of the year - $2310 in insurance premiums, 3,000 out of pocket.

    Yearly estimated total $11,320.

    2 years ago we had the corporate America special. Premium was $16,200, out of pocket was 8,000. $24,200 was the total cost. It was 26.8% of my gross income that year.
