This video was made on July 30, 2021 as the first tomatoes from these plants are ripening, before any were picked. Before making the video, I conducted a count of the number of tomatoes on each of 17 plants in the control group and 20 plants in the wood vinegar treatment group. As you may know by now, the treatment group has been sprayed weekly with a 0.5% dilution, in water, of wood vinegar, while the control group has not been sprayed. All other parameters for these 2 groups are the same, including seeding date, watering regime, fertilization, and transplanting dates.
The results of the tomato census are that the control group at this date had an average of 8.5 tomatoes per plant, and the treatment group had an average of 13.2 tomatoes per plant, which is a significant difference.
The other notable difference between the groups is that the control group has significantly fewer verdant leaves remaining at the top of the plant, many of which are already have brown spots - and had significantly more browned, completely desiccated leaves that needed to be pruned toward the bottom. The treatment group, however, still has lush foliar growth in the upper 2/3 of the plants, and while I pruned the leaves around the fruit bunches toward the bottom of the treatment group that showed signs of brown areas, none of these leaves were completely browned and dry.
