Specific Farm Uses for Wood Vinegar
The Appropriate Technology Association of Thailand recommends the following wood vinegar/water solution rates for various farm uses (ATA, p. 27-28). Note that, in some cases, no details were given regarding the specific identity of pests:
1. Repel nematodes – Tomatoes, 1:500 (apply to the base of plants);
Strawberries, 1:200 (apply to the base of plants);
black pepper vines, 1:1500 (apply in place of water).
2. Repel insect pests - Cabbage and Chinese cabbage, 1:1500 (apply in place of water);
Corn 1:300 (spray onto leaves).
3. Control of fungal diseases – Tomato and cucumber, 1:200 (spray onto leaves).
4. Control of root rot – Tomato and cucumber, 1:200 (apply to the base of plants).
5. Reduce incidence of chili pepper flowers aborting – 1:300 (spray onto leaves).
6. Improve flavor of sweet fruits and stimulate development of crops. Mix solution rates of 1:500 to 1:1000. Wood vinegar prevents excessive nitrogen levels, improves plant metabolism and contributes to higher fruit sugar levels.
7. Stimulate compost production. A solution rate of 1:100 will help increase the biological activity of various beneficial microbes and can decrease composting times.
8.Combat bad odor. A wood vinegar solution of 1:50 will diminish the production of odor-causing ammonia in animal pens.
9. Supplement for livestock feed. Mixed with livestock feed at rates of between 1:200 and 1:300, wood vinegar can adjust bacterial levels in the animal digestive tract which improve the absorption of nutrients from feed.
10. Enrich garden soil. Use a strong solution of 1:30 to apply to the garden soil surface at a rate of 6 liters of solution per 1m² to enrich the soil prior to planting crops. To control soil-based plant pathogens, use an even stronger rate of 1:5 to 1:10.
11. Repel houseflies. Dilute wood vinegar at a rate of 1:100 and apply to affected areas
