Abstract
A kind of rice seed treating agent, it is made up of active ingredient and auxiliary agent, the quality of the active ingredient accounts for the 5~85% of rice seed treating agent gross mass, the active ingredient is Shuan Ben oxazoles formic acid and gibberellin, and the auxiliary agent is the three kinds or more in surfactant, solvent, suspending agent and antifreezing agent.A kind of rice seed treating agent that the present invention is provided, Rice seeds treated, the drug resistance of the herbicides such as rice seedling Dui fenoxaprops can be improved, herbicide is improved to the selectivity between the malignant weeds such as paddy rice and Weedy Rice, ensure rice seedling rate, influence when reduction Shuan Ben oxazole formic acid is individually handled to Germination Percentage of Rice.
Description
Technical field
The present invention relates to technical field of pesticide, and in particular to a kind of rice seed treating agent.
Background technology
Paddy rice is one of main cereal crops in the world, and paddy field weed is serious, and wherein grassy weed preventing and treating is difficult, water
Rice field is efficient, safety, selective good gramineous weed weedicide have wide market prospects and commercial value.
Fenoxaprop is higher to grassy weed preventive effect, but poor to Security of rice for the rice seedling phase,
Easily there is poisoning when the rice seedlings such as seedling field or direct sowing rice field are more immature.
Isoxadifen ethyl ester, English name：Isoxadifen-ethyl, No. CAS:163520-33-0, molecular formula：
C18H17NO3, chemical name：4,5- dihydro -5,5- diphenyl -1,2- azoles -3- carboxylic acid, ethyl esters, are a kind of safeners, are usually used in carrying
Drug resistance of the high corn to herbicide.Safener has stronger selectivity, and using effect has very big difference in Different Crop.
Shuan Ben oxazole formic acid, English name：Isoxadifen (free acid), No. CAS：209866-92-2, molecular formula：
C16H13NO3, chemical name：4,5- dihydro -5,5- diphenyl -1,2- azoles -3- formic acid, also known as Shuan Ben oxazole formic acid, Shuan Ben oxazoles
Sour (free acid), is isoxadifen ethyl ester hydrolysate, also available for safener.
Gibberellin is a plant growth regulators, has promotion seed breaking dormancy, promotes the effect such as plant growth.
Rice safety agent isoxadifen ethyl ester is used in after seedling, the drug resistance of paddy rice Dui fenoxaprops can be improved,
But the drug resistance of Dui fenoxaprops also rises after such as Weedy Rice weeds touch-safe agent；Use rice safety agent Shuan Ben Evil
Azoles acetoacetic ester handles seed, the weeds touch-safe agent such as Weedy Rice can be avoided, however, during isoxadifen ethyl ester seed treatment not
Easily absorb, it is impossible to effectively protect paddy rice from poisoning.It can be played a protective role during Shuan Ben oxazole formic acid seed treatments, but to paddy rice
Emergence rate has suppression.
The content of the invention
It is an object of the invention to provide a kind of resistance for ensureing rice seedling rate and improving rice seedlings Dui fenoxaprops

| 9th group | 1.8511 |
The field plot trial of embodiment 8
Experiment is carried out in Henan Yuanyang, field prepartion of land, and fertility is suitable, and soil moisture is moderate.During preparing soil in rice field, uniformly it is sprinkled into
Weeds rice, 1kg/ mus of application rate harrows even rear sowing cultivated rice.Cultivate before seed rice sowing, the rice seed treating agent of embodiment 6
Soaked seed, it is specific as follows：Weigh the rice seed treating agent of embodiment 6, with clear water dilute 100 times, 25 DEG C, by seed：Paddy rice
Seed treatment ratio is 1:3 pairs of rice paddy seeds are soaked seed, and are stirred once per 6h, are pulled out and dry after 48h, and seeder carries out drought
It is live, 8kg/ mus of application rate.After planting sprayed water with fine-spraying belt, keep ground moistening and without ponding.After planting 15d, the leaf of rice seedlings 3
1 heart stage, sprayed 2g/ mus of 6g/ mus+penoxsuam of fenoxaprop, and spray amount is 30kg/ mus, each 18 squares of plot area
Rice, each processing is repeated 3 times, and indwelling check plot, and check plot does not spray fenoxaprop and penoxsuam.
7d, 14d, 21d after medicine, investigate each processing cultivated rice and its inter-row weed rice poisoning index.Before dispenser and after medicine
21d, 5 points of samplings of cell, investigates fresh weight.
Table 2 estimates cultivated rice poisoning class criteria
Table 3 estimates Weedy Rice poisoning class criteria
| Poisoning rank | Growth inhibition ratio (%) |
| 0 | 0 |
| 1 | 1~15 |
| 2 | 16~25 |
| 3 | 26~35 |
| 4 | 36~45 |
| 5 | 46~55 |
| 6 | 56~65 |
| 7 | 66~75 |
| 8 | 76~85 |
| 9 | 86~100 |
The rice seed treating agent of table 4 seed soaking Dui fenoxaprops and the selective visual observation of penoxsuam
21d fresh weight measurement results after the medicine of table 5
From table 2- tables 5,7d, 14d, 21d after fenoxaprop and penoxsuam is sprayed are estimated miscellaneous to cultivated rice machine
The poisoning rank of careless rice, as a result shows, 7d after medicine, 5 grades of Weedy Rice poisoning rank, growth inhibition；14d after medicine, Weedy Rice evil level
Other 7 grades, lobus cardiacus is withered, stops growing；21d after medicine, Weedy Rice 8 grades of rank of evil is gradually withered.21d determines fresh weight, weeds after medicine
Rice fresh weight inhibition is up to 76.88%, and cultivated rice suppresses to be only 6.71%.Result above shows, by entering to cultivation rice
The processing of row rice seed treating agent, can improve selectivity of the fenoxaprop to cultivated rice and Weedy Rice.
Embodiment described above, simply presently preferred embodiments of the present invention, not limits the scope of the present invention, therefore
All equivalent change or modifications done according to technical scheme described in the scope of the claims of the present invention, all should be included in the present patent application patent model
In enclosing.
