Today we introduce dichloroisooxadone, a herbicide in wheat fields.
Everyone may not be familiar with the agent dichloroisooxazone, but many people should know that dichloroisooxadone and isoxapyrone are from the same door. In 2021, dichloroisoxazone was registered in China as the original drug of dichloroisoxazone and its single-dose product, with the trade name "Fengqu".
Dichloroisoxazone is a selective herbicide of oxazolone that, by inhibiting the biosynthesis of chlorophyll and carotenoids, causes susceptible plants to be unable to photosynthesize normally, and the plants turn white, yellow, or green, thus stopping growth and dying.
Classification of the mechanism of action of herbicides in wheat fields.
Dichloroisoxaone is mainly absorbed by the roots and seedlings of plants, and is transported from the roots upwards through the xylem to all parts of the plant with transpiration, but is not transmitted downward or between leaves.
Dichloroisooxanone has systemic and contact killing effects, has both soil activity and stem and leaf activity, and has a long duration of effect, and is mainly registered in winter wheat fields in China for the control of annual broad-leaved weeds, such as camellia, Po Po Na, Po Po Na, Sow Artemisia, Chickweed, Chickweed, etc. It has no cross-resistance with all the herbicides in wheat fields and can be used for the management of resistant weeds in wheat fields.
Dichloroisoxaone can cause whitening and growth inhibition of wheat leaves in soil types with low organic matter content when exposed to heavy rain or standing water. Therefore, it is necessary to apply pesticides according to the requirements, and the test shows that dichloroisooxazone is safe for common crops such as rice, soybean, corn, peanut, mung bean, watermelon, pepper, sweet potato, etc.
Of course, in order to expand the insecticidal spectrum and give full play to the maximum effect of dichloroisooxazone, it is generally used in combination with isoproteron, which is often mentioned in the market"."Fun" + "Sumeron".Combination. The time of application is generally in the 4-5 leaf stage of wheat before winter, the weeds are basically out, and the pesticide is applied when the temperature is stable or the spring wheat returns to green to before jointing, and the drug is used as soon as possible when the temperature is stable. The dosage is generally 40ml of dichloroisooxadone + 150-160 grams of 50% isoproturon per mu, and 50ml of dichloroisooxaone + 200 grams of 50% isoproturon per mu in early spring. The above is for reference only.
