Description
Technical field
The present invention relates to technical field of pesticide, in particular it relates to which a kind of remove containing tribenuron-methyl and the compound of lactofen
Careless agent and its application in agricultural weed is prevented and treated.
Background technology
Wheat is the third-largest cereal crops that China is only second to corn and paddy, account for the 20% of national total output of grain with
On, so ensureing that wheat persistently gets bumper crops good harvest for keeping China's self-sufficiency rate of grain, ensure that national food security has important meaning
Justice.However, Wheat Production is faced with numerous threats, wherein weeds are one of most important factors.It is reported that China's wheat paddock is careless
Evil area accounts for more than the 55% of cultivated area, wherein seriously endangering area accounts for 28%, production loss is up to 15%；Meanwhile with me
The continuous improvement of state's labor cost, have become must arranging for Wheat Production using herbicide control weeds of wheat harm
Apply.
Weeds of wheat can be divided into broad leaved weed and the class of grassy weed two, although grassy weed endanger in recent years by
Step is aggravated, but broad leaved weed is still had the advantage status in northern China wheat paddock, and its main species has Descurainia sophia, shepherd's purse, wheat
The father-in-law, conical silene herb, clearvers, lamb's-quarters, small lamb's-quarters, ivy glorybind, field bindweed, lead a cow, field thistle, pivots storage, piemarker, Siberian cocklebur, summer cypress, towards day
Potentilla chinensis, wallflower, humulus grass, Lepidium apetalum, Veronica, Trigonotis peduncularis, wartwort etc..Tribenuron-methyl is that China is wealthy for preventing and kill off wheat paddock
The most important herbicide kind of leaf weeds, have dosage is few, toxicity is low, broad weed-killing spectrum, to many merits such as crop safeties.
Tribenuron-methyl, and English common name tribenuron-methyl, chemical name 2- [4- methoxyl group -6- methyl isophthalic acids, 3,5-

(3) field control effectiveness test experimental example
The field control effectiveness test embodiment foundation of the present invention《Pesticide field efficacy medicine test criterion (one) herbicide prevents and treats wheat class
Crop field weeds (GB/T 17980.41-2000)》Carry out, by field plot trial, verify indoor biometricses result of the test, together
When clear and definite two kinds of medicaments compound by a certain percentage after to the field control effects of weeds.Test method is as follows：
Cauline leaf spraying treatment before jointing, amount of liquid medicine 450L/hm after winter wheat turns green2, often handle and be repeated 4 times, plot area
25 ㎡, random district's groups arrangement.30d is investigated after medicine, and 4 sampling points, every 1m are randomly selected per cell2, every kind of weeds are investigated respectively
Fresh weight, calculate each processing preventive effect E：
In formula：PT --- chemicals treatment district weeds fresh weight；
CK --- blank district weeds fresh weight.
Experiment is carried out in Jiao Zhuan villages of Hebei province Baoding Lian Chi areas, is the wheat paddock broad-leaveds such as Descurainia sophia, shepherd's purse for examination target
Weeds, each processing dosing and preventive effect are shown in Table 3.Field control effectiveness test result shows：Compound herbicide of the present invention, having
Imitate Ingredient Amount to be less than under lactofen exclusive use dosage, the preventive effect to Descurainia sophia is 91.36%~99.37%, to shepherd's purse
The preventive effect of dish is 90.08%~99.13%, and total preventive effect is 89.87%~99.87%, and being all remarkably higher than two kinds of medicaments individually makes
The preventive effect of used time, show that tribenuron-methyl and lactofen compounding use have obvious synergistic effect, and can effectively control small
Wheatland broad leaved weed.Preferably, when tribenuron-methyl and lactofen weight ratio are 1:When 4, the preventive effect to Descurainia sophia is 95.25%
~99.37%, the preventive effect to shepherd's purse is 94.05%~99.13%, and total preventive effect is 95.09%~99.87%, and preventive effect is better than it
It is matched.It is furthermore preferred that when tribenuron-methyl and lactofen weight ratio are 1:4, and when being prepared into suspended emulsion, to Descurainia sophia
Preventive effect is 99.37%, and the preventive effect to shepherd's purse is 99.13%, and total preventive effect is 99.87%, and preventive effect is best.It is in addition, of the present invention
Compound herbicide, it is good to crop safety, quick-acting also to have the advantages that, is a kind of preferable herbicide.
The field control effectiveness test result of the tribenuron-methyl of table 3 and lactofen compounding use preventing and treating wheat paddock broad leaved weed
