Definitions
- the present invention falls within the technical field of weed treatment in sunflower crops.
- the object of the present invention is to provide a method of selective use of the herbicide imazetapir in sunflower varieties with resistance to it and its application for the control of the jopo parasitic weed.
- Said procedure consists in applying the aforementioned herbicide in Post-emergence of the crop, by conventional herbicide applicator, in defined phases of the crop development cycle and at similarly defined doses of herbicide per hectare.
- a high control of the jopo parasitic plant is achieved by applying a post-emergency herbicide and without causing damage to the sunflower crop.
- the herbicide 2- [4,5-dihydro-4-methyl-4- (1- methyl ethyl) -5-oxo-1H-imidazol-2-yl] -5-ethyl-3-pyridinecarboxylic acid known commercially as Imazetapir and developed by American Cyanamid, belongs to the family of imidazolinones (Herbicide Handbook of the Weed Science Society of America, 6th Ed. 1989, 157 and 158) and is commercially available in diluted preparations such as PIVOT, PIVOT-10 and PURSUIT (10% imazetapir). Imazetapir (Hart et al., 1991. "The imidazoline her- bicides ", CRC Press.
- Pp.247-256 controls a broad spectrum of annual and perennial, grass and dicot species in various leguminous crops such as soybeans, peanuts, peas and beans. It can be applied in these crops in Pre-sowing; Pre-emergence and Post-emergence of weeds, in doses between 30 and 125 g of active matter (m. a.) per hectare.
- Imazapir is a herbicide that is marketed under the name ARSENAL and is the isopropylamide salt (1: 1) of 2- (4-isopropyl-4-methyl-d5-oxo-2-imidazolin-2-yl) nicotini acid - co.
- this product belongs to the same herbicide family as imazetapyr (5-ethyl-2- (4-isopro-pil-4-methyl-5-oxo-imidazolin-2-yl) nicotinic acid), it is a herbicide other than imazetapir.
- imazetapir has been used so far in leguminous crops (soy, alfalfa, peas, beans) as a selective herbicide, restricted in these cases to applications in pre-sowing, - pre-emergence and post-emergence and exclusively in pre-sowing applications at low doses (20-30 g ma / Ha) for the control of jopo in sunflower cultivation.
- the present invention refers to a method of selective use of the herbicide imazetapir in post-emergence of the cultivation of sunflower varieties resistant or tolerant to this herbicide and its application in the control of parasitic weeds. jopo (Orobanche cernua Loefl./O. cumana Wa-11er).
- the method of using imazetapir, object of the present invention makes it possible to extend the possibilities of use of the herbicide, overcoming the limitations set forth above in sunflower.
- the application of the imazetapir herbicide in post-emergence cultivation of varieties resistant to this sunflower herbicide is carried out within the interval between the VIO (10 true leaves) and V18 (18 true leaves) states, between 15 and 25 days between these states. according to the ambient temperature.
- the application is usually done with a conventional applicator.
- These stages of development of sunflower cultivation are coincident with the stages of development of jopo "c" (budding and visible yolk) and "d” (bud and developed roots).
- the aforementioned treatments with imazetapir are very effective in controlling the jopo, being well tolerated by sunflower varieties with resistance to this herbicide.
- Figure 1 shows various stages of sunflower development, indicating the states from VIO to V18 as in which the post-emergence treatment of imazetapir has to be applied for jopo control.
- the effect on the efficacy in the control of O. cernua was determined in various ways in different trials:
- Example 1 The present invention is further illustrated by the following Examples which are not intended to be limiting in scope.
- Example 1 The present invention is further illustrated by the following Examples which are not intended to be limiting in scope.
- the test was carried out under controlled conditions by sowing sunflower plants with resistance to the imazetapir herbicide in 330 cubic cm pots with a mixture of soil, sand and peat in a 4: 5: 5 ratio respectively. Each pot was inoculated with 25 mg of O. cernua seeds with a 99% viability. The seedlings were grown in a chamber with 16 hours of light and at 24 ° C / 20 ° C day / night temperature. When the Plants had forty days and showed 10 true leaves (VIO) herbicide treatments were applied. The doses used were equivalent to 26.6 gm / Ha and 53.2gm / Ha. On groups of 40 plants each.
- Control 2 52 100% 100% 0% 31.7 * 2.2 31.712.2 0
- Control 1 read at the time of treatment with the herbicide.
- Control 2 read 25 days after treatment along with treatments.
