Description
Technical field
The present invention relates to a kind of for Herbicidal combinations of monocot crops and application thereof.
Background technology
The herbicide of substantial amounts provides strong guarantee for the modernization development of agricultural, effectively inhibits the danger of weeds
Evil, significantly improves farmland grain yield, and bringing huge economic benefit for world agriculture industry increases.But herbicide exists
Some problems are encountered in its application process, most prominent is its herbicide carryover and resistance weed problem.Some are removed
Careless agent also has stronger killing ability to crop, and dispenser is easily to crop generation poisoning during plant growth.Some herbicides
Residual in use can generate inhibition to the growth of second stubble crop, cause secondary poisoning.Part pesticide is in normal use
Can also poisoning be generated to crop, gently then influence yield under concentration, it is heavy then crop is caused disease even death occur.Herbicide it is big
Amount and Reusability also result in the generation of resistant weed, become increasingly difficult weeding process.
It prevents crop from being had water spray, top dressing of loosening the soil, place to go poisoning position etc. by the method for herbicide damage, but prevents medicine
Harmful effect is limited.Safener is generally added in industry at present to improve herbicide safety, expansion herbicide controlling spectrum, improve weeds
Control effect.The control of use chemical method and the relevant weeds of crop plants of safener selectivity, make non-selective remove
Careless agent can selectivity control farmland weed, first crop residual long residual herbicides are to the residual medicine of crop in antagonism crop rotation systems
Evil.Since being found from safener, safener has played important function in agricultural production, it goes profit from a new angle
With the use with the existing commercial herbicide of extension.Safener research is an important branch of herbicide research, is had wide
Development prospect and development and application market.But variety development and study on mechanism of the China in relation to safener are still in a step
Section.

Biological activity test example
Before seedling is tested：
Under greenhouse experiment, using standard soil as cultivation matrix, test plant is seeded in seedling alms bowl (diameter 8cm, depth
In 12cm), it is covered with the soil that thickness is 0.5cm.In the before seedling stage, Herbicidal combinations are administered to soil surface.Dosage depends on
In optium concentration identified under greenhouse experiment.(100% effect=plant is completely dead for evaluation test after 2-4 weeks；0%
Effect=plant-less toxicity effect).The Herbicidal combinations used in this test show good result.
It is tested after seedling：
Herbicidal Testing Trials are carried out for different types of weeds
Test method：Dress 300g standard soils, stand after adding water, are sowed after 2 days in seedling alms bowl (diameter 8cm, deep 12cm)
Weed seed is simultaneously covered with 0.5cm soil, adds water plantation a period of time.When weed growth to 3-4 leaves, by Herbicidal combinations to spray
Mist form is administered on test weeds, and dosage depends on the identified optium concentration under greenhouse experiment.Evaluation test after 5 weeks
(100% effect=plant is completely dead；0% effect=plant-less toxicity effect).The Herbicidal combinations used in this test
Show good result.
Four kinds of reagents are prepared according to constant weight percentage：1. safener+chlorine sulphur is grand；2. safener+chlorimuronethyl；3. peace
Full agent+imazethapyr；4. safener+fomesafen.Above-mentioned each reagent is diluted with water after a certain period of time, respectively observation pair
Rice barnyard grass, moleplant seed, Monochoria vaginalis, angustifolia arrowhead herb, Procumbent Falsepimpernel, difformed galingale herb herbicidal effect.
Observation is to the herbicidal effect table of rice barnyard grass after handling 5 weeks
According to result of the test as can be seen that the Herbicidal combinations of present invention herbicidal effect in the case of low usage amount is bright
It is aobvious, there is good control effect to weeds.
Embodiment 11
To the safety effect of crop
Under greenhouse experiment, by trial crops, culture is to 4 leaf phases in seedling alms bowl (diameter 8cm, deep 12cm), by Herbicidal combination
Object is administered to Sprayable on test crop, and dosage depends on the identified optium concentration under greenhouse experiment.It is evaluated after 5 weeks
(100% effect=crop is completely dead for experiment；0% effect=without crop toxic effect).Concrete condition such as following table
According to result of the test as can be seen that the Herbicidal combinations of the present invention have crop good protecting effect, do not make
Into apparent poisoning.
