Description
Technical field
The present invention relates to pesticide field more particularly to herbicide fields, and in particular to a kind of Herbicidal composition for rice field and
It is applied.
Background technology
Furans sulphur humulone belongs to benzoyl cyclohexanedione class herbicide, mainly by inhibit growing process in can not
Or scarce pigment synthesis is killed weeds, can be absorbed by root, stem, young shoot and leaf and be conducted rapidly.It is to annual and for many years
Raw weeds, including have awns cyperus iria category and have the weeds of drug resistance all largely effective sulfonylurea herbicide.Mainly
It is prevented and kill off 1 year for rice, cereal and perennial weeds and nutgrass flatsedge.
Flucetosulfuron chemical name:Chemical name:1- (- 2 base of 4,6- dimethoxypyridins) -3- [the fluoro- 1- of 2-
(methoxyl group acetoxyl group) propyl -3- pyridine sulfonyl sulfonyls base] urea.It is by LG life sciences Co., Ltd of South Korea and South Korea
A kind of sulfonylurea herbicide that chemical technology research association develops jointly.The inhibitor of acetolactate synthestase, that is, pass through
Inhibit the ALS enzymes of plant, prevents the biosynthesis of branched-chain amino acid such as valine, isoleucine, leucine, finally destroy albumen
Synthesis and cell division and the growth of DNA are interfered in the synthesis of matter.It can be absorbed by the root, stem and leaf of plant, lead to weeds
Grow stopping, chlorosis, apical meristem death.
Herbicide is the major way of current preventing and controlling weed in rice field, but applies single chemistry to continuous high dose for a long time
Herbicide, Weed Resistance, population succession and drug injury problem getting worse existing for farmland weed chemical control.Different pesticide species
Mixture, be prevent agriculture diseases, insect pests and weeds common methods.It is screened by formulation of pesticide, filters out rational formula, it can be effective
Practical control effect is improved, dosage is reduced, reduces cost, delay the generation of disease pest and weed drug resistance, is that agricultural synthesis is administered
Important means.When being directed to furans sulphur humulone and flucetosulfuron single use at present, there are certain defect and limitation.At present
There is no the compound medicines about the two, and are used for other weeding Drug Combination Effects of rice terrace nor highly desirable.

Indoor biological active determination test:
Virulence coefficient of the Herbicidal composition for rice field of the indoor measurement present invention to barnyard grass.
Test method is as follows:
Reagent agent:97% furans sulphur humulone active compound, 96% flucetosulfuron active compound;
For trying target:Barnyard grass, cyperus iria;
Experimental procedure:Using potting cauline leaf process method (NY/T1155.4-2006):In the polypots of high 6cm, diameter 9cm
Built-in quantitative soil will be placed on temperature for the 15-20 sowings of examination target weeds seed in polypots after covering the fine earth of 0.5-1cm thickness
Indoor culture waits for that weeds grew to the 2-4 leaf phases and carries out cauline leaf spraying treatment, and per alms bowl hydrojet 1mL, often processing is repeated 4 times, and is set and be free of
The processing of medicament is control.Examination is just placed in greenhouse and cultivates after processing, the growing state of routine observation target weeds, mesh after 15d
Target damage symptoms and growth inhibition situation are surveyed, and claims aerial part fresh weight or strain fresh weight, is commented with target weeds fresh weight inhibition rate
Valence medicament is to its toxicity action.
Control time:Target damage symptoms and growth inhibition situation are estimated after test process 15d, and claim aerial part fresh
Weight.
Data statistics and analysis:
According to investigation statistics, fresh weight inhibition rate (%) is calculated.
Fresh weight inhibition rate P (%)=(control fresh weight-processing fresh weight)/processing fresh weight × 100.
Synergy evaluation method:
Herbicide mode of application (NY/T1155.7-2006) is evaluated according to Gowing methods, formula is as follows:E0=X+

(%).
Evaluation criterion:Work as E-E0Synergistic effect is expressed as when > 10%, as -10%≤E-E0It is expressed as being added when≤10%
Effect, works as E-E0Antagonism is expressed as when < -10%.
The results are shown in Table 1 for toxicity test.
The joint toxicity measuring result of 1 furans sulphur humulone of table and flucetosulfuron compounding
Indoor co-toxicity test the result shows that, just to the preventive effect of barnyard grass from the point of view of, by active ingredient furans sulphur humulone and fluorine
The grand ratio of pyrrole sulphur is 1:1.5~3:When 1 compounding, E-E0> 10% shows certain synergistic effect;According to what is mentioned in upper table
- 10%≤E-E when other ratios compound0≤ 10%, summation action is shown as, and wherein furans sulphur humulone and flucetosulfuron are 1:
Synergistic effect when 1 is most apparent.Just to the preventive effect of cyperus iria from the point of view of, by active ingredient furans sulphur humulone and flucetosulfuron according to
When ratio compounds in table, -10%≤E-E0≤ 10%, show certain summation action.It is recommended that pressing suitable proportion 1:1.5~3:
1 or so complex preparation further carries out field control effectiveness test, to evaluate its field practical application effect.
Paddy field weed field control effectiveness test
Field efficacy plot experiment method is used below, is further verified furans sulphur humulone and is compounded in crop field with flucetosulfuron
Using the preventive effect to rice terrace annual gramineous weed, broad leaved weed and sedge weed.
Test medicine:The preparation-obtained Herbicidal composition for rice field of Examples 1 to 5;
Comparison medicament 1:10% flucetosulfuron suspending agent;
Comparison medicament 2:30% furans sulphur humulone suspending agent.
If artificial weeding and clear water control treatment (CK).
Application method:Uniform cauline leaf sparges in each cell after being watered 30 liters per acre.Hillslope processes are arranged using random district's groups
Row, each processing are repeated four times.
Spraying time:In the rice 7-8 leaf phases, the weeds in field 1-3 leaf phases carry out cauline leaf and spray 1 time.
Dispenser place:Jiangxi Province Yugan County
Investigation method and drug effect calculate
Investigating weeds object is:The weeds such as barnyard grass, moleplant seed, lady's-grass, Monochoria vaginalis, cyperus iria, needle spikesedge herb, 15 after investigation
It, 40 days to the strain preventive effect of weeds and 40 days fresh weight preventive effects.
The field efficacy of 2 furans sulphur humulone of table and flucetosulfuron compounding
It is preferable to broad leaved weed preventive effect that field control effectiveness test result shows that furans sulphur humulone is used alone, to standing grain such as barnyard grasses
Undergraduate course weeds and sedge weed preventive effect are slightly poor, and rationally compounding can overcome this disadvantage.Furans sulphur humulone and flucetosulfuron with
1:1.5~3:1 ratio compounding has favorable effect to rice terrace annual gramineous weed, broad leaved weed.Meanwhile the two is made
With mechanism difference, the generation that can delay herbicide resistance is rationally compounded, expands herbicide controlling spectrum, extends the medicament lasting period.Range estimation hair
Existing, each processing plant growth is normal, has no that rice plant generates apparent poisoning, illustrates that it is safety to the rice varieties of experiment
's.
To sum up indoor virulence and field control effectiveness test result verification, furans sulphur humulone be used alone to broad leaved weed preventive effect compared with
Good, slightly poor to the grassy weeds such as barnyard grass and sedge weed preventive effect, rationally compounding can overcome this disadvantage.Furans sulphur humulone
With flucetosulfuron with 1:1.5~3:1 ratio compounding has rice terrace annual gramineous weed, broad leaved weed preferably anti-
Effect.Meanwhile the two mechanism of action is different, rationally compounding can delay the generation of herbicide resistance, expand herbicide controlling spectrum, extend medicament
Lasting period.Range estimation finds that each processing plant growth is normal, has no that rice plant generates apparent poisoning, illustrates its water to experiment
Rice varieties are safe.
