2. Pendimethalin indoor proportioning screening test mixed with pyrazosulfuron
Under greenhouse experiment, pot-culture method research is utilized to compare Pendimethalin mixtures' ratio different from pyrazosulfuron
Herbicidal effect, and by Sun Yun abundant method evaluation synergy type after mixed, select to provide indoor for the most mixed and proportioning
Drug effect foundation.Test method is: quantitative grassy weed barnyard grass and broad leaved weed Eclipta prostrata seed are sowed at height respectively
For in the Disposable paper cup of 9cm, broadcasting rear earthing 0.5cm, flatten trickle and be placed in greenhouse and cultivate according to a conventional method, after broadcasting, 24 is little
Time, carry out soil by EXPERIMENTAL DESIGN dosage crawler type crops sprayer (Britain Engineer Research Ltd. designs production)
Earth spraying treatment (atomisation pressure 1.95kg/cm2, spouting liquid 500L/ha, crawler track speeds 1.48km/h).Test is repeated 4 times.Examination
Material processes to be placed in greenhouse and manages according to a conventional method.Routine observation respectively processes emerging and reaction feelings to medicament after Seedling of weeds
Condition, and weigh each process weeds aerial parts fresh weight in processing latter 21 days, calculating fresh weight preventive effect, application DPS2000 data process
Each medicament of system-computed is to linear regression equation and the ED for trying weeds90Value, evaluates the activity of weeding of different mixtures' ratio.
Reagent agent: the 95% former medicine of Pendimethalin, the 96% former medicine of pyrazosulfuron；
Test plant: barnyard grass [Echinochloa crus-galli (L.) Beauv.]
Eclipta prostrata [Eclipta prostrata (L.) L.]
EXPERIMENTAL DESIGN: Pendimethalin consumption is 30,60,120,180,240g a.i./ha；Pyrazosulfuron consumption is
7.5、15、22.5、30、45g a.i./ha；Pendimethalin is mixed from pyrazosulfuron to be tried by 5 different weight proportions
Test, proportioning 1# (1:1), proportioning 2# (3:1), proportioning 3# (6:1), proportioning 4# (9:1), proportioning 5# (12:1), consumption is 30,60,
120,180,240g a.i./ha (g a.i./ha represents effective ingredient g/ hectare).
Test determination result is as shown in Table 1 and Table 2:
The table 1 Pendimethalin different ratio mixed with the pyrazosulfuron co-toxicity coefficient to barnyard grass
The table 2 Pendimethalin different ratio mixed with the pyrazosulfuron co-toxicity coefficient to Eclipta prostrata
Result of the test shows, to grassy weed (barnyard grass) and broad leaved weed after Pendimethalin is mixed with pyrazosulfuron
(Eclipta prostrata) all has preferable preventive effect, can expand weed control spectrum, reached the purpose of one-time weeding after the two is mixed, is producing
On can save labour force, the two is mixed has certain using value.Pendimethalin and pyrazosulfuron is evaluated by the abundant method of Sun Yun
Synergy type after Hun Yong, result shows, the two all can realize common poison when proper proportion is used with to barnyard grass and Eclipta prostrata
Coefficient is noticeably greater than 100.Preventive effect and synergy result to weeds after comprehensive Pendimethalin is mixed with pyrazosulfuron,
Both suggestions are used with at Pendimethalin: pyrazosulfuron is for selecting preferably in the range of (3:1)～(9:1).
3. the estimation of stability of agent for removing grass in paddy field fertilizer granules
Embodiment 1.1-1.8 accepts the stability test of 14 days by a definite date under the conditions of 54 ± 2 DEG C, uses high performance liquid chromatography
(HPLC) the active component Pendimethalin before and after mensuration stability test and the percentage by weight of pyrazosulfuron, detection knot are analyzed
Fruit is as shown in table 3.Carry out HPLC analysis under the following conditions:
Instrument: high performance liquid chromatograph, has Variable wavelength UV detector；Chromatographic column: 200mm × 4.6mm (i.d) is no
Rust steel column, built-in C18 implant, particle diameter 5 μm；Microsyringe: 25 μ l.
High performance liquid chromatography operating condition is as follows:
Flowing phase: the volume ratio of acetonitrile and water (pH3) is 75:25；
Flow velocity: 1.0ml/min；
Column temperature: room temperature；
Detection wavelength: 236nm；
Sampling volume: 10 μ l；
Solvent: methanol；
Retention time: pyrazosulfuron 4.1min, Pendimethalin 15.7min.
Table 3 is containing Pendimethalin and pyrazosulfuron herbicide fertilizer granules estimation of stability (14 days)
From bin stability result it can be seen that herbicide fertilizer granules with nitrogen-potassium compound fertilizer as carrier, effective ingredient
The heat storage resolution ratio of Pendimethalin and pyrazosulfuron is below 5%；Herbicide fertilizer granules with carbamide as carrier, effectively becomes
The heat storage resolution ratio dividing Pendimethalin and pyrazosulfuron is above 10%, so nitrogen-potassium compound fertilizer is as the load of this Weed removal medicinal fertilizer
Body stability is more preferable.
4. Application Example
In order to preferably verify the practical application effect of the present invention, illustrate that one of the present invention is containing diformazan penta with example below
Happy spirit and pyrazosulfuron herbicide fertilizer granules prevent and kill off paddy field weed test of pesticide effectiveness result.
Experimental condition:
Test site: Kuai great town, Tonghua, Jilin Province county
