Problems solved by technology

This one-time treatment does control plant height, however, occasional reductions in plant yield have been found, especially when plants are stressed during or after use

example 1

[0340] An aqueous mixture of 4.2% by weight of mesoquat and 560,000 CFU / ml of Bacillus cereus (laboratory sample BP01, ATCC55675) was prepared in a volume ratio of 1:1. Cotton plants in a test plot in Field A (10 of 50 acres, Mississippi) and a test plot in Field B (8 of 60 acres, Tennessee) were sprayed with 4 sprays of the solution using a conventional sprayer on the leaves. Field A was treated with one dose of 4 ounces of fluid per acre followed by 8 ounces of fluid per acre for 5 weeks.

[0341] Daejeon B has a different treatment plan. The first 3 applications for Field B were 4 ounces of fluid per acre (24 hours between 1st and 2nd applications. 6 days between 2nd and 3rd applications). The last application in Field B was 11 days later at 8 fluid ounces per acre. In all cases, the control field was treated with the same amount of metropine only.

[0342] After treatment, samples were taken from Fields A and B by hand in representative rows. All known biases were bro...

example 2

[0356] Bacillus cereus strain BP01 (ATCC55675) was used in combination with the widely used herbicide atrazine to determine whether BP01 would affect the control of weeds that are recognized as difficult to kill with triazines. Atrazine is used to produce one-season control of corn, sorghum, and other crops at a recommended rate of 2 pounds of active ingredient per acre. At a sufficiently high dosage, such as the dosage of this example, it can be found that atrazine has non-selective weed control ability.

[0357] In sandy soils, each test was performed in triplicate in plots 12 feet by 25 feet in random complete enclosures. Weeds were 2-6 inches (5-15 cm) tall at the time of treatment. Atrazine is used in an aqueous solution at an amount equivalent to 1 or 2 pounds of active ingredient per acre. Dilute BP01 concentrate at the equivalent of 0.5 or 1 ounce of fluid per acre (0.5-1×10 10 The consumption of CFU / acre) is added in described atrazine. For comparison, a crop oil ...

Abstract

An agriculturally effective active ingredient is applied to plant foliage before, after, or simultaneously with an enhancer component containing a substantially pure bacterial culture, suspension, spores, or cells of a bacteria selected from the genus Bacillus or a soil bacteria.

Description

field of invention [0001] The present invention relates to the treatment of plants with a composition comprising an agriculturally effective active ingredient and a fortifying additive comprising a substantially pure culture of bacteria selected from the group consisting of Bacillus or soil bacteria. The added culture can be in the form of cells, spores, or a suspension. Background of the invention [0002] Pesticide manufacturers are always looking for ways to increase the potency of active ingredients used on plants. This is particularly desirable when the material used is a plant growth regulator (growth inhibitory or growth promoter), herbicide or systemic agent (eg, insecticide or fungicide). The transport mechanism into the plant and transfer between various plant tissues is important and, in some cases, may be a major factor in determining the potency of the ingredients used. For some active ingredients, improved transport mechanisms may manifest as increased effica...
