product description

Whole plant

50 g / liter (100 g / liter) diflufenacil SC

The agent has good hydrophobicity, membrane permeability, anti-metabolic stability and high biological activity due to factors such as fluorine atom. It shows the advantages of low dosage, wide herbicidal spectrum, good miscibility, safety to wheat, especially low temperature resistance, and it is still effective at -2 °C. The disadvantage is that the speed of dead grass is slow, it takes 7 to 10 days under normal conditions, and 40 to 50 days under bad conditions. In order to maximize the advantages of diflufenacil, one is to use the weeds at a young age, and the other is to mix with other agents.

Mai Xi, Prui Mai

58 g / liter (175 g / liter) of difluoro-oxazolamide SC

Maixi is the first marketed product of diflufenate compounding agent. The formula has a wide spectrum of herbicides, and can prevent most broad-leaved weeds such as pork mites, Maijiagong, Fanling, sown wormwood, and leeks, and has certain inhibitory effects on lacquer. It has good control effect on malignant weeds, Maijiagong, pig mites and resistant sage. It is stable at low temperatures and stable even at 2 °C. The application period is wide, and can be used from the 2 leaf stage to the early stage of the jointing (before the second node is pulled out). However, its lethal rate is slow, and the low temperature reduces the lethal speed. At the same time, because of the long-lasting residual soil, the pyrisulfuron in Maixi has a certain risk to the post-leaf broad-leaved crops. Maixi's medication was better than early spring medication. Areas that have developed resistance to bensulfuron should be appropriately increased

Full autumn

43% difluoro·2 methyl 4-chloroisooctyl ester SE

The formula is located in the drought-and-dry rotation area in the resistance broadcasting sage, resistant sputum menu hair or mixed area. The water and drought rotation area is located in the menu or mixed area of ​​the swine fever and resistant cockroaches. The full autumn specification is 100 ml/bottle, and 1 bottle per acre. It can effectively prevent resistant leeks, resistant buds, etc. If there are resistant weeds, lacquer, and sorghum at the same time, add chlorofluoperoxyacetic acid 30-50 ml per mu. It can dispose of common broadleaf weeds in wheat fields at one time. It can be used before winter and early spring. It is generally best after wheat 4 leaf stage to 2 internodes. The effect is still good at low temperature, and it can be applied at the lowest temperature of 5 °C. However, it should be avoided in extreme weather conditions such as frost, snowfall, etc., which are drastically cooled from 1 day to 3 days before use. Since the full autumn contains 2 to 4 chlorine components, it is not recommended to mix with aryloxyphenoxypropionate herbicides such as benzoxazole and acetylene. Compared with Maixi, it obviously speeds up the speed of killing grass, and has better control effect on amaranth, but it is easy to cause volatile and drifting phytotoxicity to sensitive crops around the periphery. It is used at low temperature, and it is easy to use wheat before and after 3 weeks of wheat. Produce phytotoxicity

Mai Shida

459 g / liter of difluoro·2,4-diisooctyl ester SC

The formula has a wide spectrum of herbicides, such as porcine, sorghum, sage, sage, maijiagong, wheatgrass, leeks, alfalfa, ragweed, mustard, alfalfa, alfalfa, alfalfa, and leeks. Both have good control effects; especially the resistant insects and leeks have good control effects; but their dead grass is slow. Low temperature does not affect the final weeding effect, but it affects the speed of effectiveness; Mai Shida also needs to pay attention to its actual field performance and safety. Compared with Maixi, it obviously speeds up the speed of killing grass, and has better control effect on amaranth, but it is easy to cause volatile and drifting phytotoxicity in sensitive crops around the periphery, and it is used at low temperature.
Pay attention to the use: First, the application period is from 4 leaves of wheat to before jointing; second, the minimum temperature at the time of application is not lower than 5 °C, preferably above 8 °C, 1 day before administration to 3 days after administration. There are zero-degree low temperature, frost, snowfall and other bad weather, to avoid the application of drugs; third is not recommended to mix with oxazolazine, acetylene herb; fourth is the moderate sensitivity or root system (Asteraceae) weeds Such as Mai Jiagong, Bao Gaicao, Po Po Na, Xiao Yan, etc., it is recommended that the medication period should be sooner rather than later, except for small and old

Sharp super wheat

20% difluoro·fluorochloropyridine ester WG

Acre dosage: 5 ~ 6.7 grams + special additives. Characteristics: 1 It has excellent performance on weeds such as swine fever, sage, and leeks, which have strong resistance, and has higher safety to wheat. 2 Its new mechanism of action can effectively prevent resistant weeds, such as ALS resistance, glyphosate resistance and triazine-resistant weeds. It has no effect on wheat growth and is safe. 3 broad spectrum of killing grass: swine fever, resistant swine fever is not limited by leaf age, application temperature. The effect of the seedlings of Artemisia scoparia and the resistant sage was good. It can also prevent difficult-to-control broad-leaved weeds such as young wild sedge, resistant to stagnation, ox-fan, maijiagong, mother-in-law, and lacquer. 4 Even under adverse conditions such as low temperature and drought, the effect is still stable, and the systemic conduction does not recur. 5 applicable period width

Chunjie

15% difluoro·chloroflupirate SE

The formula is located in the control of resistant leek, pork chop, sorghum / beef sorghum, lacquer, big nest and so on. Weeds can be used after emergence, without leaf age restrictions, can be mixed with other grass or broadleaf weed herbicides, and will not affect the eucalyptus broadleaf crops. Low temperature does not affect the final weeding effect, but it affects the speed of effectiveness. Chunjie improved the slow speed of diflufenacil and the short-term effect of flufenoxyacetic acid on temperature and the poor control effect on amaranth. It showed a wide period of medication and could effectively control a variety of weeds. Convolvulus is extremely effective and safe for wheat

Jin Zhi + Ma Ling

Diflufenazone + 2 methyl 4-chloroisooctyl ester

It has a wide spectrum of herbicides, and it has good control effects on broadleaf weeds such as wormwood, leeks, piglets, maijiagong, sorghum, and sugar mustard, especially for ALS-resistant wormwood and leeks. The control effect is also good; the quick-acting effect is good, the effect is effective 3 days after the drug, and some deaths have been made 6 days after the drug; the long-lasting effect period can prevent the broad-grain damage during the growth period of wheat in one application; the control effect is good, the large Part of broad-leaved weeds have a control effect of more than 95%; high safety, occasionally contact-killing remedies, recoverable 15 days after drug administration; still show good control effect at low temperature; good safety after application is better than before winter Apply. However, it is sensitive to dicotyledonous crops such as broad bean and rapeseed, and prevents the liquid medicine from drifting when used in wheat fields, causing harm.

Wheat straw

11.5% diflufenacil (1.5%)·Naproxen (10%) WG

This product is a new compound preparation of diflufenacil and sulfimsulfuron. It is used to feed the sage, leeks, lepidoptera, alfalfa, swine fever, acid mold leafhopper, flat storage, field convolvulus, and borage in the wheat field. Evidence-resistant broad-leaved weeds are more effective in controlling the annual broad-leaved weeds in the wheat field; the recommended dose is safe for buckwheat and lower glutinous corn. The wheat can be used from the 2nd leaf to the booting stage, and it is better to use the wheat from the winter to the spring tillering stage. In the 3~5 leaf stage of winter wheat, the weeds are applied in the 2~5 leaf stage. Before the jointing of wheat, 1 bag of 20 grams per mu is used, 15 kg of water before the year, conventional spray treatment

McDonald's

459 g / liter of difluoro (6 g / liter) · octyl octyl ester (453 g / liter) SE

This product is a new compound double-endostatic conductive herbicide with diflufenacil and 2,4-diisooctyl ester. The synergistic effect of the compound preparation is obvious; it is used to control broadleaf weeds, leeks and wilds in wheat fields. Rape, piglet, etc. are difficult to prevent weeds, and have a very good inhibitory effect on the lacquer that is difficult to control in the wheat field. It is resistant to the special effects of the wormwood, leeks and wild rapeseed; this product can be transmitted to the whole weeds, so It kills the grass thoroughly and does not recur; its biggest advantage is that it is stable at low temperature; in addition, its squat interval is short, and it can be rotated for other crops at intervals of 2 months; stems and leaves are quickly absorbed by weed stems and roots after treatment And conduction in the body, affecting tissue cell division, causing weeds to die. Before winter, in the 3~5 leaf stage of wheat, 2~5 leaf stage of broadleaf weeds, before the jointing of wheat, use 1 bottle per acre, 15 kg of water, evenly spray on weed stems and leaves.
