Pyrimidine urea compound containing isoxazolines and use thereof

FIELD OF THE INVENTION

The present invention relates to herbicide. Specifically to a kind of uracil compounds containing isoxazoline ring and the uses thereof.

BACKGROUND OF THE INVENTION

The research of uracil derivatives as herbicides began in the 1960s and peaked in the 1990s. Although the development of uracil herbicides were seldom reported, some patents of uracil derivatives were often disclosed. Isagro Ricerca disclosed the following general formula in WO2004056785. However, the herbicidal properties of these known compounds are not always entirely satisfactory.

##STR00002##

Wherein: Q.sub.1 was 5-membered heterocycle such as oxazolyl, thiazolyl, benzoxazolyl, benzothienyl, benzothiazolyl, etc. Q.sub.2 was F or H.

Even though some similarity can be observed between published compounds in the prior art and the present invention compounds, the compounds having the structure of general formula (I) were different significantly from those in prior art, and have good herbicidal activity as well.

SUMMARY OF THE INVENTION

In order to discover and develop new herbicides for solving the increasing problem of resistance, the present invention provides a kind of uracil compounds containing isoxazoline ring and the uses thereof.

In order to achieve the above object, technical solution of the present invention is as follows:

Test of Biological Activity

Example 18 Bioassay of Herbicidal Activity in Greenhouse

Determination of herbicidal activity of compounds of the present invention against weeds was carried out by the following procedures:

Seeds of monocotyledonous and dicotyledonous weeds were sown in nutrition soil in paper pot (7 cm diameter), covered with soil in 1 cm and grown in the greenhouse under good growth conditions (temperature, atmospheric humidity, water supply). The compounds of the present invention as emulsifiable concentrate, were applied in pre-emergence and post-emergence treatment by track sprayer (Engineer Research Ltd., pressure 1.95 kg/cm.sup.2, volume 500 L/hm.sup.2, track speed 1.48 km/h). Pre-emergence treatment was conducted after seeding 24 hours and post-emergence treatment was done when the respective weeds reached predetermined leaf stage (grass weed 2- to 3-leaf stage, broad-leaf weed 2- to 4-leaf stage), the state of growth of the respective weeds were visually observed to determine the growth inhibition rate (%) in accordance with the following evaluation standard.

Growth inhibition rate (%): 0=no discernible action: 100=all weeds dead or not emerged.

The results of general screening showed that compounds 4, 5, 6, 7, 8, 10, 15, 16, 17, 22, 23, 26, 35, 42, 43, 45, 46, 50, 54, 55, 66, 67, 83, 88, 90, 96, 99, 282, 284, 286, 290, 320, 321, 323, 324, 328, 329, 332, 333, 345, 366, 396, 397, 398 had a good pre-emergence and post-emergence herbicidal activity against broad-leaf weeds and grass weeds at 1000 g a.i./hm.sup.2.

Pre-emergence treatment was conducted after seeding 24 hours and post-emergence treatment was done when the respective weeds reached predetermined leaf stage (soybean and cotton at 2- to 4-leaf stage and maize, wheat and rice at 3-leaf stage), the state of growth of the respective crops were visually observed to determine the safety in accordance with the following evaluation standard.

Safety rating scale (%): 0 means no damage to crops; 100 means to kill crops completely.

The results showed that wheat, maize and rice have good safety to compound 43, 45, 46, 83 at 7.5-37.5 g a.i./hm.sup.2 with pre-emergence and post-emergence application.

Example 21 Field Trial

The field trial was conducted in an orchard located at Liaoyang city, Liaoning province, China; the orchard planted mainly apple trees and almond trees, plum trees and pear trees as well, weeding control were conducted three times one year by application of paraquat. Weeds were distributed uniformity and moderate density, mainly of broad-leaf weeds including Conyza canadensis (L.)Cronq., Sonchus brachyotus DC., Polygonum aviculare L., Humulus scandens (Lour.) Merr., Ixeridium sonchifolium (Maxim.) Shih, Galium aparine L. var. tenerum Gren. et (Godr.) Rebb., Rumex japonicus Houtt. and Metaplexis japonica (Thunb.) Makino, partly of grass weed was Digitaria sanguinalis (L.) Scop., average height range was between 30 and 40 cm. sprayer was knapsack hand-operated sprayer(AGROLEX HD400) produced by AGROLEx PTE Ltd., spray volume was 675 L/hm.sup.2, processing date was Jul. 3, 2015. On the 15th day after application, weeds were visually observed to determine the growth inhibition rate (%).
