Abstract

The invention relates to a weeding compositions and weeding method for a garlic field. The weeding compositions provided by the invention is characterized in that 55 parts by weight of 24% oxyfluorfen and 45 parts by weight of 96% Kingduer are mixed to obtain a broad leaved weed weeding composition; 29 parts by weight of 24% oxyfluorfen and 71 parts by weight of 33% stomp prowl are mixed to form a graminaccae and broad leaved weed weeding composition; and 29 parts by weight of 24% oxyfluorfen, 24 parts by weight of 25% oxadiazon and 47 parts by weight of 50% acetochlor are mixed to form a worst weed weeding composition, herein the oxyfluorfen is wide in application range, wide in weed control spectrum, long in validity, less in Mu dosage and high in activity, and can be matched with various weed killers, thus the weeding compositions provided by the invention have the advantages of enlarged weed control spectrum, improved drug effect and low toxicity, are convenient to use, and can be used for weeding in the garlic field more thoroughly, more safely and more reliably.

Description

Garlic field weeding composition and herbicidal methods

Technical field

The present invention relates to a kind of garlic field weeding composition and herbicidal methods.

Background technology

Garlic field crop smothering kind is many, take place early, generating capacity is big, the harm phase is long, thereby the difficulty of preventing and kill off is also bigger.Adopt chemical weed control, it uses kind, use age and dosage must be very accurate, does to such an extent that bad meeting produces poisoning.

Oxyfluorfen is fluorine-containing phenylate class weed killer herbicide, and its activity of weeding improves 5～10 times than corresponding nitrofen, and the scope of application is wide, broad weed-killing spectrum, the lasting period is long, and the mu consumption is few, active high, can use with multiple mixture of herbicides, enlarge and kill the grass spectrum, improve drug effect, easy to use, but both bud pre-treatments, but bud post processing again, toxicity is low.

Summary of the invention

The purpose of this invention is to provide a kind of garlic field weeding composition and herbicidal methods, make the weeding in garlic field more thorough, safe, reliable.

The present invention is achieved by the following measures:

Herbicidal combinations proportioning of the present invention is (in a weight portion):

All you mix with 55: 45 ratios for 24% Oxyfluorfen and 96% gold medal, form the broad leaved weed Herbicidal combinations;

24% Oxyfluorfen and 33% is executed the field and is mended with ratio mixing in 29: 71, forms grass family and broad leaved weed Herbicidal combinations;

24% Oxyfluorfen, 25% oxadiazon and 50% Acetochlor mix with 29: 24: 47 ratios, form the malignant weed Herbicidal combinations.

Using method:

(1) the broad leaved weed Herbicidal combinations is converted suitable quantity of water, even spraying before broadcasting the back seedling is removed the broad-leaved weeds;

(2) grass family and broad leaved weed Herbicidal combinations are converted the suitable quantity of water even spraying, grassy weed and the mixed field of giving birth to of broad leaved weed are carried out weeding;

(3) the malignant weed Herbicidal combinations is converted the suitable quantity of water even spraying, remove malignant weed such as clearvers, ox chickweed etc.

The invention has the beneficial effects as follows: the Oxyfluorfen scope of application is wide, broad weed-killing spectrum, and the lasting period is long, and the mu consumption is few, active high, use with multiple mixture of herbicides, enlarge and kill the grass spectrum, improve drug effect, easy to use, toxicity is low, makes the weeding in garlic field more thorough, safe, reliable.

The invention will be further described below in conjunction with embodiment.

Embodiment 1

Mu is converted 40 kilograms in water with 24% Oxyfluorfen 60ml and all that 50ml mixing of 96% gold medal, and even spraying before broadcasting the back seedling is to remove the field broad leaved weed.

Embodiment 2

Mu is executed the field with 24% Oxyfluorfen 60ml and 33% and is mended 150ml and mix, and converts water and evenly sprays for 40 kilograms, can mix living field to grassy weed and broad leaved weed and carry out weeding.

Embodiment 3

Mu is converted water with 24% Oxyfluorfen 60ml, 25% oxadiazon 50ml and 50% Acetochlor 100ml and is evenly sprayed for 50 kilograms, and malignant weed clearvers, ox chickweed etc. is had special efficacy.

Claims (2)

1. garlic field weeding composition and herbicidal methods is characterized in that:

Herbicidal combinations proportioning of the present invention is (in a weight portion):

All you mix with 55: 45 ratios for 24% Oxyfluorfen and 96% gold medal, form the broad leaved weed Herbicidal combinations;

24% Oxyfluorfen and 33% is executed the field and is mended with ratio mixing in 29: 71, forms grass family and broad leaved weed Herbicidal combinations;

24% Oxyfluorfen, 25% oxadiazon and 50% Acetochlor mix with 29: 24: 47 ratios, form the malignant weed Herbicidal combinations.

2. according to the described a kind of garlic of claim 1 field herbicidal methods, it is characterized in that:

(1) the broad leaved weed Herbicidal combinations is converted suitable quantity of water, even spraying before broadcasting the back seedling is removed the broad-leaved weeds;
