Crop enhancement
The present invention relates to a method of enhancing a crop by applying to plants, plant parts, plant propagation material or a plant growing locus, a compound of formula (I), which is a compound of formula (Ia), (Ib), (Ic), (Id), (Ie) or (If): where each R 1 , R 2 and R 3 is independently selected from H, Cl, F, Br and CF 3 ; each R 4 is independently selected from CH 3 , Cl, Br and CF 3 ; and each R 5 is independently selected from where R 6 and R 7 are each selected from Cl, Br, CH 3 , CH 2 CH 3 , CF 3 and OCF 2 H; R 8 is selected from F and OCH 3 ; R 9 is selected from H, CH 3 and CH 2 CH 3 ; and R 10 is phenyl optionally substituted by F or Cl; where R 11 and R 12 are each selected from Cl, Br, CH 3 , CH 2 CH 3 , CF 3 and OCF 2 H; each R 13 is independently selected from Cl and Br, each R 14 is independently selected H, CH 3 and CH 2 CH 3 ; each R 15 is independently selected from H and CN; and each X is independently selected from CH and N; or a composition comprising a compound of formula (I).
1 . A method of enhancing a plant by increasing resistance to an abiotic stress factor, comprising:
identifying a plant propagation material or a plant growing locus for the plant propagation material exhibiting or susceptible to the abiotic stress factor; and
applying to the plant propagation material or the plant growing locus, an effective amount of an active ingredient of a compound of formula (Ia), or any isomer thereof
or a composition comprising the compound of formula (Ia);
wherein the abiotic stress factor is cold temperature exposure or increased salinity.
2 . The method according to claim 1 , wherein the plant is a cereal, a pulse, canola or corn.
3 . The method according to claim 1 , wherein the plant is wheat.
4 . The method according to claim 3 , wherein the compound of formula (Ia) is applied at seeding as a seed or soil treatment.
5 . The method according to claim 1 , wherein the plant is corn.
6 . The method according to claim 1 , wherein the plant is a crop of transgenic plants.
7 . The method according to claim 1 , wherein the compound of formula (Ia) is applied before the appearance of a stress factor.
8 . The method according to claim 1 , where the compound of formula (Ia) is isocycloseram.
9 . The method according to claim 8 , wherein the compound of formula (Ia) or the composition thereof is applied to corn seeds under low temperature.
10 . The method according to claim 8 , wherein the compound of formula (Ia) or the composition thereof is applied to wheat seeds under increased salinity.
11 . The method according to claim 1 , wherein the cold condition is about 15° C.
12 . The method according to claim 1 , wherein the plant propagation material germinates in cold conditions at a T50 of about 90.61%-93.1% compared to an untreated plant propagation material.
13 . The method according to claim 1 , wherein the plant propagation material germinates in cold conditions with a uniformity of about 191%-233% compared to an untreated plant propagation material.
14 . The method according to claim 1 , wherein the plant propagation material germinates in cold conditions at a rate of about 105%-106% compared to an untreated plant propagation material.
15 . The method according to claim 1 , wherein the salinity is about 12.5 mM.
16 . The method according to claim 1 , wherein the plant propagation material germinates in increased salinity at a T50 of about 95.27%-93.07% compared to an untreated plant propagation material.
17 . The method according to claim 1 , wherein the compound of formula (Ia) is applied at a concentration of about 25-125 μM.
18 . The method according to claim 1 , wherein the compound of formula (Ia) is the sole active ingredient to increase resistance said abiotic stress factor.
