Abstract
A herbicide for corn field is prepared from dicamba and atrazine in weight ratio of 1:(1-80) through mixing them with assistant and carrier, and preparing emulsion, suspension, wettable powder, or powder. Its advantages are broad spectrum, high effect, and high safety.
Description
The present invention relates to agricultural chemicals, specifically a kind ofly prevent and kill off the weeds in field preparation by dicamba (dicamba) and salt thereof and atrazine (atrazine) combination.
The active ingredient that the present invention relates to:
Dicamba (dicamba)
Atrazine (atrazine)
The objective of the invention is to provide a kind of composite weedicide that the single, double cotyledon weeds in field is all had better preventive effect.
Herbicide formulations of the present invention is to be the Herbicidal compositions of active ingredient preparation by dicamba and salt thereof and atrazine, is used for the disposable single, double cotyledon weeds that corn field takes place of preventing and kill off.It is characterized in that: dicamba by weight ratio: atrazine is 1: 1～1: 80; Add appropriate amount of addition agent or carrier, be prepared into suspended emulsion, suspending agent, wetting powder, pulvis.
Advantage of the present invention:
(1) enlarge grass spectrum extremely, and have significant synergies: dicamba, atrazine list are used corn field broadleaf weed preventive effect better, and be relatively poor to the monocotyledon weed preventive effect.But both use with and show significant synergistic effect, and single, double cotyledon weeds are all had better preventive effect, can disposablely prevent and kill off single, double cotyledon weeds in the corn field, weeds in the dispenser controlled corn whole growing.
(2) to working as stubble corn and succession crop safety: the composition that the present invention proposes, reduced the consumption of atrazine, use by the doubly amount of normal field consumption through verification experimental verification, not only to when the safety of stubble crop corn fine, and after the medication to the equal safety of the crops such as wheat of back stubble plantation.
Part embodiment of the present invention:
Example 1 (wetting powder):
Dicamba 1%, atrazine 79%, filler 14%, auxiliary agent 6% is made 80% wetting powder.
Example 2 (pulvis):
Dicamba 3%, atrazine 47%, filler 44%, auxiliary agent 6% is made 50% pulvis.
Example 3 (aqueous suspension agent):
Dicamba 20%, atrazine 20%, filler 20%, auxiliary agent 8%, water supplies 100%, makes 40% aqueous suspension agent.
Example 4 (aqueous suspension agent):
Dicamba 8%, atrazine 32%, filler 20%, auxiliary agent 8%, water supplies 100%, makes 40% aqueous suspension agent.
Embodiments of the invention preparation weeding test effect sees the following form:
| Handle medicament | Consumption (gai/ha) | To lady's-grass, eleusine indica, green foxtail preventive effect (%) | To Amaranthus retroflexus, kitchen garden preventive effect (%) | |
| Example 1 medicament | ????1140 | ????81 | ????93 | |
| Example 2 medicaments | ????1050 | ????92 | ????94 | |
| Example 3 medicaments | ????420 | ????74 | ????96 | |
| Example 4 medicaments | ????720 | ????95 | ????98 | |
| The contrast medicament | Dicamba | ????216 | ????52 | ????92 |
| Atrazine | ????1140 | ????68 | ????86 | |
More than handle the equal safety of corn.
Claims (1)
