BIOLOGICAL EXAMPLES
(53) A) Reduced Plant Water Use in Soybean
(54) Compounds were tested for their effect on reducing plant water use as follows. Each compound was dissolved in a blank emulsifiable concentrate (EC) formulation that was then diluted to the desired concentration with water containing additional surfactant (EXTRAVON 1 g/20 L). The compounds were applied by foliar spray to 12 day old soybean plants (variety S20-G7) grown in controlled environment plant growth chambers. Plant water use during the day was assessed by repeated weighing of the pots in which the plants were grown before and after application of the compounds at the indicated times (expressed in days after application (DAA)). The water use data before application was used to correct any differences in water use arising due to non-treatment effects (e.g. due to differences in plant size). The untransformed water use values were subjected to an analysis of covariance, fitting the effect of treatment and using the baseline water use 1 day before application as a covariate.
(55) The results are expressed compared to negative control treatment (diluted EC formulation without active ingredient but with EXTRAVON 1 g/20 L).
(56) Application of the chemicals (0 DAA) takes place approximately between 08:00 and 09:30 a.m. WU is measured within day time (chamber light is on 06:00 to 20:00) at these timepoints: 0 DAA a.m. (10:30-12:50), 0 DAA p.m. (14:00-19:50), 1 DAA a.m. (7:30-12:50), 1 DAA p.m. (14:00-19:50), 2 DAA a.m. (07:30-12:50) and 2 DAA p.m. (14:00-19:50). The cumulative total WU (0-2.5 DAA) is calculated by summing the WU data mentioned above.
