Abstract
A herbicide for corn field is prepared from sulcotrione and atrazine in weight ratio of (1-80):(1-80), as well as assistant and carrier. Its advantages are low cost and high effect.
Description
The invention belongs to the composition of preventing and kill off farmland weed, be mainly used in corn field, be pesticidal preparations.
The weed killer herbicide of corn field seedling post processing mainly contains at present: Yu Nongle (nicosulfuron): the former industry of Japanese stone company Development and Production, very high at the Chinese market cost, every mu can reach 15～20 yuan.Prevent and kill off most of grassy weeds and part broad leaved weed behind the corn field seedling.Because beautiful agricultural happy cost is higher, so though enter Chinese market and also do not accepted for a long time by the user of China.
Atrazine: can before bud or behind the bud, use, prevent and kill off annual weed in the corn field, main better to the preventive effect of broad leaved weed in the corn field, relatively poor to the grassy weed effect, especially after the phase, almost do not act at grassy weed 2 leaves.
So the weed killer herbicide in the present corn field behind the seedling can not be controlled the generation of weeds in the corn field completely effectively, brings great inconvenience to agricultural production.Seeking a desirable corn field herbicide after seedling, is many pesticide research persons and users' dream for many years.
The purpose of this invention is to provide a kind of better at corn field postemergence weed control effect, be easy to the weed killer herbicide that the peasant accepts, promptly sulphur humulone and atrazine are mixed prevents and kill off the corn field weed preparation.
The active ingredient that the present invention relates to:
The sulphur humulone
Sulcotrione (C
14H
13CLO
5S)
328.8 Atrazine atrazine (C
8H
14CLN
5) 215.7
Herbicidal formulations of the present invention is by sulphur humulone (sulcotrione) and the binary mixture of atrazine (atrazine) for the active ingredient preparation, contains effective composition weight proportion in this mixture and is:
The sulphur humulone: atrazine is 80: 1～1: 80; Add appropriate amount of addition agent or carrier.
Auxiliary agent is agricultural newborn 500#, agricultural newborn 600#, dimethylbenzene; Carrier is methylcellulose, kaolin, dimethyl methyl acid amide, sodium alkyl sulfonate, precipitated calcium carbonate, water.
Add in the mixture common auxiliary agent or carrier routinely preparation technology be made into missible oil, wetting powder, pulvis, aqua, colloidal suspending agent etc.
Advantage of the present invention:
(1) save drug cost: the composition that the present invention proposes, can disposablely prevent and kill off in the corn field from seedling stage (1 leaf, 1 heart) to the late growth stage most of grassy weeds and the broad leaved weed of (6 leaves are about the phase).Weeds in the dispenser controlled corn whole growing.Saved farming season, relatively happy with the beautiful farming of corn field herbicide after seedling simultaneously, the mu cost drops to below 10 yuan/mu from 15～20 yuan/mu, has saved drug cost, is easy to the peasant and accepts.
(2) enlarge grass spectrum extremely: the post processing of atrazine seedling is effective to broad leaved weed, to the grassy weed poor effect.And the sulphur humulone is all fine to single broadleaf weed effect in the 2.5 leaf phases of weeds when following, but poor slightly to above the average age for marriage broad leaved weed effect, after atrazine mixes, can prevent and kill off weeds behind all seedlings that comprise above the average age for marriage broad leaved weed fully.The two is used with, kills the complementation of grass spectrum, and has certain synergistic effect.
Part embodiment of the present invention
Example 1 (wetting powder):
Sulphur humulone 10%, atrazine 50%, methylcellulose 5%, precipitated calcium carbonate 35% is made 60% wetting powder.
Example 2 (wetting powder):
Sulphur humulone 1%, atrazine 79%, methylcellulose 5%, kaolin 15% is made 80% wetting powder.
Example 3 (wetting powder):
Sulphur humulone 50%, atrazine 5%, methylcellulose 5%, kaolin 40% is made 55% wetting powder.
Example 4 (missible oil):
Sulphur humulone 4%, atrazine 30%, agricultural newborn 500#5%, agricultural newborn 600#5%, dimethylbenzene complements to 100%, makes 34% missible oil.
Example 5 (aqua):
Sulphur humulone 35%, atrazine 0.5%, dimethyl formamide 10%, sodium alkyl sulfonate 5%, water 49.5% is made 35.5% aqua.
Example 6 (colloidal suspending agent):
Sulphur humulone 5%, atrazine 40%, sodium alkyl sulfonate 5%, agricultural newborn 600#5%, water 45% is made 45% colloidal suspending agent.
Preparation of the present invention sees the following form to the weeds preventive effect:
| Handle medicament | Consumption (gAI/ha) | To barnyard grass grass, lady's-grass preventive effect % | To piemarker, knotweed preventive effect % | |
| Example 1 medicament | ????1200 | ????100 | ????100 | |
| Example 2 medicaments | ????1200 | ????60 | ????100 | |
| Example 3 medicaments | ????600 | ????95 | ????100 | |
| Example 4 medicaments | ????1200 | ????100 | ????100 | |
| Example 5 medicaments | ????600 | ????90 | ????100 | |
| Example 6 medicaments | ????900 | ????95 | ????95 | |
| The contrast medicament | The sulphur humulone | ????600 | ????85 | ????90 |
| Atrazine | ????1500 | ????10 | ????70 | |
More than handle the equal safety of corn; 2～4 leaf phases of weeds.
