Agriculture


No one knows better than the farmer the problems with water shortage. One of our products in particular can help with this very real concern. Another can help hold a pesticide or fungicide in plant contact for long periods of time, or be used as a substitute for pesticides.





MOISTURIN (not recommended for plants during bearing periods)

Long known as the best of the foliar anti-transpirants Moisturin is now being touted as an extremely effective as an overall plant protector. We are hearing from growers suggesting that Moisturin is replacing their need for many pesticides and fungicides. Click here to see how.




ROOT-ZONE (GRAS material. No EPA or FDA restrictions)

An entirely new concept in anti-transpirants and it really works. We have the test results to prove it. Root-Zone is drenched into the soil, rather than sprayed on the plant and it can reduce your watering needs by over 40%. Root-Zone can double the shipping and display life of tomatoes, lettuce, peppers, and celery plants. Root-Zone should also be applied prior to planting of plugs into the field.

Transportation of Agricultural Bedding Plants

Young bedding plants are suffering from desiccation during transportation from seedling growers to farmers. Several trays containing celery, lettuce, and watermelon seedlings drenched with aqueous solutions of 2.5% and 5% ROOT-ZONE a day before scheduled transportation. After making a round trip from Oregon State to Idaho State in June, 1993, the conditions of the seedlings were observed.

The bedding plant seedlings treated with formulations of the present invention suffered less than 5% damage and remained in a sellable condition, while the control plants suffered more than 50% damage from desiccation. The normal expected damage for one-way transportation from Oregon to Idaho State is 30% to 40% during hot months of June and July.

Transpiration in Tomato Plants

The efficacy of the present invention is demonstrated by results showing reduction in transpiration rate of tomato plants. Water losses by transpiration of the tomato plants and by evaporation of the soil moisture were determined.

Two trays each containing ten young tomato seedlings along with another set of trays without plants were treated with an aqueous solution of 0.5% ROOT-ZONE and DI water. Each tray was weighed three days after the treatments. Average water losses of a tray without plants (water loss by evaporation only), a tray with 0.5% ROOT-ZONE treated plants (water loss by evaporation and transpiration), and a tray with DI water treated plants (water loss by evaporation and transpiration) were 26 grams/day, 37 grams/day, and 45 grams/day respectively. The transpiration rates per plant were 1.9 grams/day/plant for DI water treated plants and 1/2 grams/day/plant for ROOT-ZONE treated plants. The root drenching with an aqueous solution of 5% ROOT-ZONE reduced the transpiration rate of young tomato seedling more than 35% as listed in Table 1.

The efficacy of the present invention is also demonstrated by experiments showing that the plants conditioned with the present invention are hardier against drought stress. A set of four tomato plants per each treatment including control was transplanted to 4-inch (in diameter) pot 29 days after the last treatment. After uniform soil water conditions were established, watering was stopped for a week.

Tomato plants conditioned 31 days prior to the water denial remained turgid and have dark green leaves while unconditioned plants (control plants) are severely wilted.

This long-lasting conditioning effect has been confirmed by an outside university evaluation. A set of 22 week old and plug-grown seedlings was treated with two sequential applications of an aqueous solution of 1% ROOT-ZONE. The treated plants exhibited a very rapid growth inhibition relative to the control plants. The difference was apparent within several days. After an additional two weeks, the plants in the plugs were transplanted into 6-inch standard pots to evaluate seedling response to water stress. After soil water conditions were established, water was withheld and plants were observed daily to evaluate the effects of the present invention. After ten days without water, the difference between treated and control seedlings was remarkable and distinct. Untreated plants were severely wilted, while treated plants remained turgid and had dark green leaves. There was no lasting growth inhibition, however, and time differences in leaf turgor do not appear to be related to differences in plant size.

We dipped filbert cuttings in various concentrations up to 50% Moisturin. There were five replicates with 12 cuttings each in treatment. All Moisturin treatments improved the percentage of cutting having both roots and buds, with the high concentration nearly doubling the percentage.

Moisturin Maize Tests in Kenya

Dear Mr. Glessner,
We are using the Moisturin to test its ability to reduce excessive evapotranspiration in Maize at selected stages of maize growth and development. We are using the principle that maize is very sensitive to moisture stress at certain critical stages of its growth, while during the vegetative development, it can withstand drought to some extent without affecting final yield. Thus by applying Moisturin at vegetative stages, the conserved soil moisture can be available during later stages when maize is at peak demand for moisture ie the critical stages. The rainfall characteristics in Kenya are such that, it comes at start of the season when farmers plant but disappear for 3-4 weeks when the crop is at its peak water requirement. The high ambient temperatures equally aggravate the situation in terms of increased atmospheric demand and therefore excessive evapotranspiration, both from soil and plant surfaces. In the end, crop failure occurs, and the vicious cycle of hunger and poverty repeats it-self every year. I have a strong belief that from previous tests with Moisturin, we can conserve enough water in the soil or improve crop-water relations to a favorable state to bridge the water demand at the critical stages and thus increase food production in the region. The Important thing is timing. The current crop is 7 days old and will be foliar applying Moisturin in 13 days time. Thanks
