Abstract
A herbicide for corn field is prepared from dicamba and linuron in weight ratio of 1:(1-75) through mixing them with assistant and carrier and preparing emulsion, suspension, emulsified oil, 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 lorox (linuron) combination.
The active ingredient that the present invention relates to:
Dicamba (dicamba)
Lorox (linuron)
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 lorox, 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: lorox is 1: 1～1: 75; Add appropriate amount of addition agent or carrier, be prepared into suspended emulsion, suspending agent, missible oil, wetting powder, pulvis.
Advantage of the present invention:
(1) enlarge grass spectrum extremely, and have significant synergies: dicamba, lorox 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 when stubble corn and succession crop safety: through verification experimental verification, the composition that the present invention proposes is used by the doubly amount of normal field consumption, 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%, lorox 74%, filler 19%, auxiliary agent 6% is made 80% wetting powder.
Example 2 (pulvis):
Dicamba 4%, lorox 46%, filler 44%, auxiliary agent 6% is made 50% pulvis.
Example 3 (aqueous suspension agent):
Dicamba 20%, lorox 20%, filler 20%, auxiliary agent 8%, water supplies 100%, makes 40% aqueous suspension agent.
Example 4 (missible oil):
Dicamba 7%, lorox 33%, auxiliary agent 8%, solvent 52% is made 40% missible oil.
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 | ????1350 | ????76 | ????94 | |
| Example 2 medicaments | ????1050 | ????93 | ????96 | |
| Example 3 medicaments | ????420 | ????82 | ????92 | |
| Example 4 medicaments | ????720 | ????96 | ????98 | |
| The contrast medicament | Dicamba | ????216 | ????52 | ????92 |
| Lorox | ????1500 | ????65 | ????87 | |
More than handle the equal safety of corn.
Claims (1)
