preparation example Construction
[0439] In some embodiments, the combination comprises both paraffin oil and water. It is advantageous to administer such a combination as an oil-in-water (O / W) emulsion. In some embodiments, a method of preparing an oil-in-water emulsion comprises: mixing paraffin oil and water and any other components and paraffin oil, and shearing until the emulsion is obtained.
[0440] In other embodiments, the combination may comprise two or more separately contained (eg, packaged) compositions, each composition comprising one or more of the components described above. The compositions may be mixed and applied to an area of the growing medium with or without prior dilution with water; or the compositions may be applied separately, simultaneously or sequentially, to the same area of the growing medium, and each combination The substances can be applied independently with or without prior dilution with water.
[0441] In the above-described embodiments, any one (or more) compositions ...
Embodiment 1
[0521] Example 1: Evaluation Study on Greenhouse Stem Rust
[0522] Under greenhouse conditions, the Civitas were tested TM Alone or with Harmonizer TM Combination, efficacy in controlling wheat (Triticum aestivum 'Norin43') infection caused by Puccinia graminis f.sp. tritici ("Pgt"). Briefly, each treatment consisted of four pots containing four plants. The plants were planted on March 2. As shown in Table 7, when the days before inoculation (DBI) of inoculation (March 17) was 7 days (March 10), Civitas was applied by foliar spraying. TM 、Harmonizer TM and their combinations were applied to the test plants. The mean severity of infection, expressed as % infected leaf area, was assessed on March 29, 12 days after inoculation.

Embodiment 2
[0524] Embodiment 2: the research of wheat stem rust
[0525] Tested Civitas between May and July TM Alone or with Harmonizer TM 、Folicur TM or Quilt TM Combination, efficacy in controlling wheat (Triticum aestivum 'Norin43') infection caused by Puccinia graminearum ("Pgt"). Use Roundup on May 9th TM Treat a test field and till it twice before planting. On May 28, several plots were sown at a seeding rate of 1.25 bushel / acre, bu / A. These plots were all 15 feet (ft) long and 5 ft wide in 7 rows . Due to flooding of the test field shortly after planting, the test area was reduced to 7 ft long and then divided into small alleys. Multiple plots and experimental units consisting of highly rust-susceptible spreader mixes alternated with each other.
[0526] The trial design was 5 parallel trials in a randomized complete plot. Administer Puma on June 10 TM (0.4 pints per acre (pt / A)) and Bronate Advanced TM (0.8pt / A) to control weeds. Pgt uredospores were collected from n...
