Description
Technical field
The present invention relates to technical field of pesticide combination, contains isoxaflutole, atrazine and topramezone more particularly to one kind
Herbicidal combinations.
Background technology
Isoxaflutole is a kind of organic heterocyclic class selectivity internal-suction type seedling that soil treatment is done for the Dry crop such as corn, sugarcane field
Pro-herbicide, mainly worked via weeds young root Assimilation and conductivity.After susceptible weeds absorb this medicine, by suppressing to hydroxyl
Base propiophenone dioxygenase and destroy the formation of chlorophyll, cause aggrieved weeds chlorosis to be withered.Isoxaflutole apply when or administration
Afterwards, though the active ingredient being stranded in because soil moisture content is bad in topsoil can not give play to the effect of management of weeds in time,
But remain to be kept for the long period be not decomposed, rainfall or irrigation to be run into, remain to play the effect of management of weeds, or even to growing to
The susceptible weeds of 4~5 leaves also can be killed and suppressed.The lasting period of isoxaflutole is moderate, and the half-life period in soil is shorter,
Usual noresidue basic after 4 months, therefore there is no bad influence to succession crop.
Atrazine is the selective before seedling of interior suction, herbicide after seedling.Based on being absorbed with root, cauline leaf absorbs seldom, is transmitted to plant rapidly
Separate living tissue and leaf portion, photosynthesis is disturbed, makes weeds lethal.In the resistance crop body such as corn, decomposed and generate by corn ketolase
Innocuous substance, thus to crop safety.
Benzene carfentrazoneethyl is a kind of contact killing type selective herbicide, causes the product of poisonous intermediate by suppressing proporphyrinogen oxidase
It is tired, so as to destroy the cell membrane of weeds, blade is dried up rapidly, be dead.Herbicide speed is fast, small by low temperature effect, medication machine
Can be wide, because azoles humulone has good low temperature resistant and resistance of rainwater washing against effect, can medication when temperature drops to very low before the winter, also may be used
In rainfall, frequently spring gets the jump on the timely medication in rainy day gap, and fool proof to succession crop, and it is excellent to be that wheatland spring eliminates
Good herbicide.
Rational chemical herbicide compounding or mixture, which have, expands herbicidal spectrum, improves prevention effect, extends the optimum period for applying fertilizer, reduces and use
Dose, poisoning is reduced, reduces residual, delays the positive features such as drug-fast generation and development, mixture of herbicides or mixture are solutions
Certainly one of maximally efficient method of above mentioned problem.We screen and on the basis of field test, filter out isoxazole grass indoors
Ketone, atrazine and topramezone compound, and have obvious synergistic effect.And on isoxaflutole, atrazine and topramezone
The Herbicidal combinations of compounding and application there is no people to report at present.

Embodiment
To make technical scheme, purpose and advantage are more clearly understood, and the present invention is said with specific examples below
It is bright, but the present invention is not limited to these examples.The effect experiment of the present invention is by the way of field test, unless otherwise instructed,
Ratio mentioned below is all quality parts ratio.
Field control effectiveness test
It is moderate to test the humidity at Wheat in Henan Province field proving ground, the consistent middle fertility of soil fertility, experiment, experimental field mainly
Weeds have clearvers, bromegrass etc., and weeding control effect is uniform.Result of the test is as follows：
The isoxaflutole of table 1, atrazine and topramezone compounding field efficiency test
Field experiment result shows that isoxaflutole, atrazine and topramezone are compounded to wheat paddock grass family, broad-leaved with ratio
The preventive effect of the weeds such as grass is preferable, is estimated according to field, and in the range of test dose, plant growth is normal, has no that plant produces
Poisoning and anomaly, it is safe to wheat to illustrate it.
To sum up result of the test is verified, the Herbicidal combinations of the invention containing isoxaflutole, atrazine and topramezone, main to use
Broad leaved weed, grassy weed are prevented and kill off in preventing and kill off wheat paddock, and to Target crops safety, compared with single dose, weeding group of the present invention
Compound has the mechanism of action unique, there is that dosage is few, and weeding is general more extensively, and the lasting period is longer, the obvious advantage such as more environmentally-friendly.
So research and development and popularization of the invention have great social effect and environment protection significance.
