Description
Technical field
The present invention relates to herbicide technology fields, and in particular to a kind of to contain gibberellin class compound with synergistic activity
Glyphosate class Herbicidal combinations.
Background technique
General glyphosate is with its wide spectrum, environmentally friendly and less toxic and become the most important herbicide in the world, due to its tool
There is particular mechanism of action, causing weeds to generate it, resistance is very slow, it was widely applied from 1974 between 20 years in 1993,
Never about the report of glyphosate-resistant weeds.However after 1996, with a series of transgenosis glyphosate resistant crops
Expand plantation, revolutionize the previous use pattern of glyphosate, start it is single and before crop sprout and sprout after etc. no
It being repeated as many times and uses with growth and development stage, using more prevalent, dosage dramatically increases glyphosate, glyphosate is used for multiple times every year,
No-tillage area is caused to expand.Depending on unduly and being used for a long time for same mechanism of action herbicide, certainly will will lead to weed control
It falls transition and generates resistance, under selection pressure effect, weeds generate resistance or patience to it and will significantly increase.It is careless in recent years
Sweet phosphine faces enormous challenge and pressure.
Firstly, weeds produce resistance to glyphosate.In the long-term a large amount of high-intensitive selection pressure for using glyphosate
Under, have found that 28 kinds of resistance glyphosate weeds, the weeds such as especially common Chenopodiaceae and amaranth are fast in the farmland of multiple countries and regions
Fast resistance rapid development.China also occurs much showing glyphosate resistant weeds, as in the wheatland of North China ivy glorybind,
The dominant weeds such as field bindweed, wartwort, the Conyza canadensis etc. of Ningbo of Zhejiang, field thistle, meadow pine, lettuce pod dish in orchard etc. are perennial miscellaneous
Grass, it is no longer sensitive to glyphosate.
Secondly, significant changes occur for weed community.Weeds are under the selection pressure of glyphosate, although weeds are to glyphosate
Resistance continues to develop, but since there is differences to glyphosate-tolerant for different weeds, therefore weed population changes specific resistivity bion
More frequently become apparent from.Such as continuous application glyphosate 3 years or more, in sweet potato field, Conyza canadensis, thorn lettuce, summer cypress, Siberian cocklebur amaranth, Chenopodiaceae,
Salsola collina etc. is increased, and in cotton field Soybean Field, the annual grassy weeds such as amaranth, dayflower, knotweed, sweet potato, herba setariae viridis, piemarker and nutgrass flatsedge become
Main weeds.
Third, controlling weeds unit dose increase.Glyphosate bioactivity is high, and dosage is low, and price and unit area use
It is at low cost, be its sales promotion and use the advantages of one of.Dosage under normal circumstances, orchard, plantation spray effective component 50
~100 grams/acre, farmland sprays 20~80 grams/acre of effective component, forestry, road, garden or wasteland spray effective component 75~
200 grams/acre, add 15~40 liters of water, dilutes 200~300 times by spraying.But it in recent years, is caused miscellaneous with the frequent use of glyphosate
Grass increases the patience of glyphosate, and present dosage reaches original 3~8 times, even more than 8 of normal usage times or more, dilute
It releases multiple and is reduced to 100 times or less.By taking 41% glyphosate isopropylamine salt water solution as an example, 150~300 milliliters of dosage per acre originally,
Present 200~900 milliliters of dosage per acre.
In addition, in production application, since herbicidal effect reduces glyphosate under conventional formulation rate, in order to improve grass
The herbicidal effect of sweet phosphine, user arbitrarily with other herbicides or non-farm chemical ingredients mixture, arbitrarily increase dosage, change user
Method etc., leading to problems such as crop occur, phytotoxicity, person poultry poisoning, pollution environment, effect is poor occurs often.
Gibberellin is a kind of auxin being widely present in plant, and also known as gibberellic acid, chemical structure belongs to two
Terpene acid is obtained by four ring skeletons derivative.Artificial synthesized gibberellin is a plant growth regulators, same that there is adjusting to plant
The substance of object physiological effect.At least 38 kinds of gibberellin type, it can stimulate the growth and development of plant, have in some aspects compared with
Good effect, effect most outstanding is to accelerate the elongation of cell, also has facilitation to the division of cell, it can promote cell
Expand, in addition to this, gibberellin, which also has, breaks seed dormancy, stratification, can make long-day plant under the conditions of short-day
It blooms, shorten life cycle, can induce and bloom, increase melon male flower number, induced parthenocarpy improves fruit-setting rate, promotes fruit
Grow directly from seeds long, delayed fruit aging, prevents organ from the physiological actions such as falling off.It is widely used in agricultural production, stimulates the life of leaf and bud
It is long, improve yield.
