AI Could Conquer the Superweeds

“Bayer and rivals like Corteva and Syngenta say new AI systems are helping speed up the lengthy, complicated and costly process of bringing new chemicals to market. Their efforts include not only new herbicides for weeds but novel fungicides and insecticides as well. Syngenta estimates that AI will reduce the average time from discovery to commercialization by a third—to 10 years from 15 years—and likely decrease the number of lab and field tests by 30%.

Bayer is using an AI system, internally named ‘CropKey,’ to help match the protein structure of a weed with a chemical molecule that targets that structure by sifting through data faster than humans. Molecules selected with CropKey’s help could have a higher success rate during field testing than conventional research, Reiter says. It gives the company an edge—like counting cards in a game of blackjack—and is similar to how drug companies are using AI to speed up the search for molecules that target a particular disease.”

Global Food Prices Ease amid Improved Supply and Trade

“Global grain supplies are projected to reach a record 3.6 billion tons in the 2025-26 season, marking a third consecutive year of growth—though at a slower pace than the average annual growth of the preceding two decades. Wheat supply has returned to its long-term average growth rate, while maize supply has rebounded after recent setbacks but remains below its historical trend. In contrast, supplies of rice and soybeans are projected to grow at about their long-term growth averages, building on last season’s significantly elevated levels.”

England Poised to Green-Light Precision Breeding

“The UK government is close to approving rules for precision-bred plants in England. In May, Parliament published draft legislation that will enable a new regulatory system, as set out in the Genetic Technology (Precision Breeding) Act 2023.

Precision breeding involves introducing genetic changes into the DNA of plants or animals using techniques such as gene editing. The new regulatory framework aims to introduce gene-edited plants with characteristics such as reduced need for pesticides and fertilizers, lower emissions, and reduced costs for farmers. Because the genetic changes are limited to what may have been obtained through traditional breeding, precision-bred crops pose no greater risk to health or the environment than traditionally bred crops. As such, the new regulatory framework will be distinct from that governing genetically modified organisms (GMOs), which involve inserting foreign DNA into the genome.

If the draft is approved by both houses of Parliament, the rules will allow the commercial use of gene editing. It will enable plant scientists and breeders to develop varieties of crops with traits that confer resilience to climate change, disease resistance, or enhanced nutrition. Those crops might include oilseed crops enriched in ω-3 oils, non-browning potatoes to reduce food waste, tomatoes enriched with vitamin D3, and strawberry plants with five times the yield.”

Lab-Grown Salmon Gets FDA Approval

“The FDA has issued its first ever approval on a safety consultation for lab-grown fish. That makes Wildtype only the fourth company to get approval from the regulator to sell cell-cultivated animal products..

Wildtype salmon is now on the menu at Haitian restaurant Kann in Portland, Oregon, and the company has opened a waitlist for the next five restaurants to stock the fish. It joins Upside Foods and Good Meat, two companies with permission to sell cultivated chicken in the US, while Mission Barns has been cleared by the FDA but is awaiting USDA approval for its cultivated pork fat.”

My Expensive, Exhausting, Happy Failed Attempt at Homesteading

“Everybody knows that drought is bad for growing things, but it wasn’t until last year that I learned heavy rain following drought is also bad, at least for tomatoes. The dry weather causes their skin to lose elasticity, and the sudden increase in moisture causes them to swell and burst. The fruit is still edible if you pick it fast enough, but a tomato becomes bug bait as soon as its insides are exposed. Crops don’t wait, and they often don’t keep.

This is one of the many lessons we’ve learned since leaving our concrete stamp in Philadelphia for three green acres in North Carolina in 2022. My wife and I initially relocated to be closer to family and because we wanted a yard where our kids could play. But as we acclimated to the greenery of the Piedmont, our appetites grew. We wanted more than a yard; we craved the full pastoral.

And so we bought a property with a large perennial pollinator garden, fruit trees, numerous trellises, a lengthy blueberry hedge, nine large raised beds and the pièce de résistance: a Lord & Burnham greenhouse built over the top of the walkout basement. We saw the house for the first time on a Wednesday. By Sunday, we were under contract and fantasizing about a homestead, where we would strive for self-sufficiency: growing and raising most of what we eat.

But three years later, most of the produce and all of the animal protein our family of five eats comes from Costco, Walmart or our local farmers market. Homesteading was simply not for us — though it did reinforce for me the miracle of modern agriculture.”
