Abstract
The present invention relates to a recipe for mixing two sterilant herbicides of glyphosate and paraquat. The recipe is characterized in that active ingredients of glyphosate and paraquat are reduced according to proportion, and the proportion of the glyphosate amine salt to the paraquat anions is 100: 4 to 100:40. Compared with the glyphosate singly used, the composition has high weeding speed. The required grass killing time is shortened to 5 to 6 days from 15 to 20 days in low temperatures seasons of winter and spring, the weeding effect is good, and the medicament cost reduces 10%.
Description
The present invention relates to the formula technique that two kinds of steriland herbicide glyphosates and paraquat are used with.
Glyphosate is a kind of inner sucting conduction type steriland herbicide, to weeds particularly perennial weed good preventive effect is arranged, but its drug effect is slow, particularly the Winter-Spring low temperature season uses, take 15-20 days weeds and just begin death, unfavorablely control weeds fast and effectively, also be not easy to the peasant and grasp spraying time flexibly.And paraquat is the quick-acting steriland herbicides of a kind of contact killing type, and it is very fast to kill careless speed, and 2-4 days weeds promptly are killed behind the general medicine, but in the weeds body inconductivity, often cause that grass is not thorough extremely, particularly to the perennial weed weak effect.
Purpose of the present invention just is that the two can accelerate the careless speed of killing of glyphosate in suitable proportioning, do not influence the interior suction conduction of glyphosate again with the use that is mixed of glyphosate and paraquat, and it is fast that perennial weed is killed careless speed, kills grass thoroughly.
A kind of composition that contains glyphosate and paraquat of indication of the present invention its essence is and refer to contain glyphosate (comprising glyphosate amine salt and glyphosate isopropyl amine salt) and two kinds of materials of paraquat (having another name called paraquat) in the same preparation that its effective ingredient ratio is glyphosate (a folding glyphosate amine salt): paraquat (folding paraquat cation)=100: 4-40.Wherein the grasp of the ratio of paraquat is very important, and ratio is low excessively, can not play the purpose that careless speed is killed in effective quickening; Ratio is too high, easily causes weeds to be subjected to medicine part withered rapidly, thereby influence absorption and the conduction of weeds to glyphosate, causes that to kill grass not thorough.The ratio of paraquat has much relations with use temperature in season height and weather conditions in the mixture, and low temperature overcast and rainy day uses season, and the paraquat ratio can improve, and the ratio of paraquat also has certain relation with the weeds population regional and that prevent and kill off of applying simultaneously.
The invention has the advantages that, by using with of glyphosate and paraquat, improved the careless speed of killing of glyphosate greatly, shortened to 5-6 days at the dead careless required time of Winter-Spring low temperature season by 15-20 days, herbicidal effect is unaffected, and drug cost descends 10%.
Embodiment: reach 10 liters in aqua (being equivalent to contain glyphosate amine salt 3500 grams) with 41% farming, 3 liters in 20% Gramoxone aqua (being equivalent to contain paraquat cation 600 grams), above-mentioned two kinds of materials are stirred the composition (batch production is produced only should adopt two kinds of former medicine processing of material certainly) that promptly obtains indication of the present invention, and the mixture usage amount is 250-300 milliliter/mu to perennial grass generally; To annual careless 100-200 milliliter/mu.
Test shows: prevent and kill off amur foxtail with 100 milliliters/mu of above-mentioned compositions mid-February, 6 days preventive effects reach 95.4% behind the medicine, and farming reaches and singly just begins death with 14 days weeds behind 125 milliliters of/mu medicines, and preventive effect just reached 94.8% in 20 days.
Prevent and kill off weeds wild Radix Artemisia ordosicae for many years in by the end of April with 250 milliliters/mu of above-mentioned compositions, 5 days weeds begin death behind the medicine, 11 days preventive effects reach about 95% behind the medicine, and 13 days weeds just begin death after singly reaching 300 milliliters of/mu medicines with farming, and 23 days weeds preventive effects just reach about 95% behind the medicine.
Claims (3)
1, a kind of Herbicidal combinations is characterized in that said composition is mixed glyphosate and paraquat, and its active ingredient proportioning is glyphosate (a folding glyphosate amine salt): paraquat (folding paraquat cation)=100: 4-40.
2, according to the Herbicidal combinations of claim 1, glyphosate wherein: paraquat=35: 6.
3, according to claim 1 and 2 described Herbicidal combinations, it is characterized in that glyphosate bag glyphosate amine salt and glyphosate isopropyl amine salt.
