~92.01%, but it is relatively low to the prevention effect of annual broadleaf weed, and fomesafen is to Chinese rose field annual broadleaf weed
Prevention effect be 84.32~88.13%, the prevention effect to grassy weed is relatively low, by haloxyfop-r-methyl and fluorine sulphur
800 times are diluted after 2: the 1 ratio mixing by volume of amine grass ether, is not reduced to broad leaved weed prevention effect, but to grass family
The prevention effect of weeds has the decline of certain amplitude, illustrates that two kinds of herbicides should not be used in mixed way, but by fomesafen,
Haloxyfop-r-methyl, cyhalofop-butyl proportioning (mass ratio) are 800 times of dilution after 1: 2: 2 mixing, and the preventing and treating to broad leaved weed is imitated
Fruit does not decline, and grassy weed prevention effect is not also declined, conversely also certain increased trend.
The conclusion of the experiment obtained around the technical problem to be solved in the present invention is：In this trial stretch, efficient fluorine pyrrole
The spirit of first standing grain, cyhalofop-butyl have preferable prevention effect to the annual undergraduate course weeds of Chinese rose field, its more than 400 times dilution
Liquid, poisoning is not produced.The broad leaved weed of Chinese rose field is viewed and admired to be prevented and treated using fomesafen, its extension rate should not be low
In 800 times.In this trial stretch, haloxyfop-r-methyl is mixed with fomesafen, and single dose pair is reduced to a certain extent
The prevention effect of Chinese rose field annual gramineous weed, the prevention effect influence on broad leaved weed is not notable, illustrates that two kinds are removed
Careless agent should not be used in mixed way.But it is 1: 2: 2 mixed by fomesafen, haloxyfop-r-methyl, cyhalofop-butyl proportioning (mass ratio)
800 times are diluted after conjunction, the prevention effect to broad leaved weed does not decline, and grassy weed prevention effect is not also declined, phase
Instead also show certain synergistic effect.According to 250g/L fomesafen, 108g/L haloxyfop-r-methyl, 100g/L
Cyhalofop-butyl, the proportioning (mass ratio) of water are 1: 1.8~2.2: 1.8~2.2: 1580~1620, with every 667 square metre 45~55
Kilogram dosage, spray on Chinese rose and weeds, to Chinese rose without poisoning.According to small area result of the test, on the one hand save
One of dispenser process, on the one hand improves the prevention effect to weeds, improves labour productive forces, meet national energy-saving, environmental protection,
The industrial policy of low-carbon, can the popularization and application in production.
