Abstract
The method for reducing crop damage, composition and the method for preparing such composition are disclosed, the composition for containing one or more safeners to crop applying and a kind of herbicidal composition containing proporphyrinogen oxidase (PPO) inhibitor are passed through.In specific aspect, safener combination contains cloquintocetmexyl and/or mefenpyrdiethyl.
Description
Invention field
The theme of the disclosure is related to Pestcidal compositions and formulation art, the safener group being especially used together with herbicide
Close object and preparation.
Background technology
More preferably one of the method for weeds controls after being related to the emergence of weeds in control crop, wherein makees in problem
Object goes out postemergence application herbicide from soil.Control is ideal after emergence, because this is needed in the area for weed infestation occur
Apply herbicide in domain.On the contrary, control then requires the Growing season early stage before most of weeds rudiments to apply weeding before emergence
Agent, the result is that these chemicals must be in entire Field information, even if this is not needed finally.
Proporphyrinogen oxidase (PPO) is the enzyme being found in plant and animal, is responsible for the conjunction of protoporphyrin IX biology

Material and method
In order to study safe effect of one or two kinds of safeners to crop, by the carfentrazoneethyl of 25 or 50g ai/ha
Or the fluthiacet joint cloquintocetmexyl of 5.6 or 11.2g ai/ha* adds mefenpyrdiethyl, cloquintocetmexyl adds naphthalic anhydride,
Mefenpyrdiethyl adds naphthalic anhydride, and mefenpyrdiethyl, cloquintocetmexyl or naphthalic anhydride are applied together.Safener cloquintocetmexyl,
Mefenpyrdiethyl and naphthalic anhydride are applied with 6.6,27.2 and 74.1g ai/ha respectively.Other processing include that azoles is administered alone
Ketone grass ester or fluthiacet.The nonionic table of 0.25% (v/v) is added in all carfentrazoneethyls and fluthiacet processing
Face activating agent.Carfentrazoneethyl is applied to crop after planting 10 days and fluthiacet is handled.Wheat and weeds are mixed with Mei Lite
Object (metro-mix) is closed to plant in 3 " plastic tubs.With compressed air track spray chamber, with 30GPA processing, using
The TeeJet 8001E nozzles of 40PSI.Minitab statistical softwares are used to data, are analyzed with 95% confidence interval.?
In 95% confidence interval, the average in each grading section of the identical wheat damage percentage of letter is not significantly different.
* naphthalic anhydride is not included in fluthiacet research.
Crop damage is assessed with range estimation grading method.Scoring of this method based on 0-100%, wherein 0% indicate without
Damage, 100% indicates that crop is completely dead.Table 1 shows the Linear assessment amount that can be used for assessing Weeds distribution or crop damage
Table.(based on Frans etc., 1986 revisions).It is considered commercially acceptable less than or equal to 10% crop damage.It is less than
Or crop is indicated not by notable harmful effect equal to 20% Injury score, and rapid and recovery completely.It is commercially acceptable
Crop damage level is different in Different Crop.Any 20% level of damage of being higher than is usually commercial unacceptable
's.
In our current research, it with safener/herbicide treatment, observes that crop damage is commercially unacceptable and is reduced to quotient
Acceptable level in industry.

In 95% confidence interval, the average in each of identical wheat damage percentage of letter grading section is not aobvious
Write difference.
Wheat damage is assessed with above-mentioned range estimation grading method.Wheat damage percentage causes small according to PPO inhibitor
It is wheat blade brown stain (bronzing), sallow and downright bad grade.These are PPO inhibitor typical diseases caused by sensitive plant
Shape (brown stain, sallow and downright bad).
In all researchs, processing is compared with carfentrazoneethyl individually processing.It is in the table and other tables statistics indicate that, it is right
The degree of injury of wheat weakens since one or more safeners are added.For example, at 3DAT (number of days after processing), 25g
It is 34% to the damage of wheat caused by the carfentrazoneethyl of ai/ha, and carfentrazoneethyl and safener in contrast, such as cloquintocetmexyl
Application is then less than or equal to 10% to+mefenpyrdiethyl together.
Unrelated with carfentrazoneethyl ratio, there are wheat damages when safener to be less than or equal to 12%, in addition to being used alone
Naphthalic anhydride, damage are more than 35% in 3DAT.Carfentrazoneethyl individually leads to 34% and 43% respectively at 25 and 50g
It damages (table 2 and 3).

No matter it is shown the results show that carfentrazoneethyl ratio and grading interval (3 and 7DAT), two kinds (Jagger and
Huangshi) cloquintocetmexyl add mefenpyrdiethyl or cloquintocetmexyl individualism when wheat damage be 13% or lower (table 4).
Similar results are seen in the carfentrazoneethyl and cloquintocetmexyl of premix.It is mixed with tank or premixed form applies mefenpyrdiethyl
The damage (table 4) higher than 20% is caused with two kinds of carfentrazoneethyl pair of 50g.With the carfentrazoneethyl of 25g or 50g without adding
The damage of two kinds of safener pair is respectively greater than 35% or is more than 40% (table 4).
Weeds distribution percentage determines with the method similar with the rating system of above-mentioned 0-100%, repeat again below for
With reference to convenient.Same Weeds distribution rating system also seen in《Research method in Weed Science》("Research Methods

Wheat when mixed object applies damages percentage
In two tests (1 and 2) shown in table 7, fluthiacet is administered alone under two kinds of ratios to wheat Huangshi
Kind cause damage (>=10%), when fluthiacet is administered alone with 5.6g ai/ha to Jagger wheats be it is safe (≤
10%).In test 1, when fluthiacet is applied together with safener alone or in combination, in 14DAT for Huangshi
(1) and Jagger is safe.When testing 1, control piemarker and morning glory in all cases (data are not shown).It is surveying
In examination 2, when fluthiacet and cloquintocetmexyl are applied plus mefenpyrdiethyl as the mixed object of tank together using 5.6 or 11.2g,
It is safe for Huangshi (2) when 14DAT.The fluthiacet of 5.6g and any safener are all in 14DAT for Huangshi
Safety.
