Description
Technical field
The present invention relates to herbicide technology field and in particular to a kind of have SA containing gibberellin class compound
Glyphosate class Herbicidal combinations.
Background technology
General glyphosate with its wide spectrum, environmentally friendly and low toxicity and become the most important herbicide in the world, due to its tool
There is particular mechanism of action, resistance is very slow to lead to weeds that it is produced, from extensively applying within 1974 between 20 years in 1993,
Never with regard to the report of glyphosate-resistant weeds.But after 1996, with a series of transgenosis glyphosate resistant crops
Expand plantation, revolutionize the conventional use pattern of glyphosate, start single and before crop sprout and after sprouting etc. no
Repeatedly use with growth and development stage, glyphosate use more prevalent, consumption dramatically increases, and glyphosate is used for multiple times every year,
No-tillage area is led to expand.Same mechanism of action herbicide is depended on unduly and Long-Time Service, weed control will certainly be led to
Fall transition and generation resistance, and under selection pressure effect, weeds produce resistance to it or patience will significantly increase.Grass in recent years
Sweet phosphine faces enormous challenge and pressure.
First, weeds create resistance to glyphosate.High intensity selection pressure in substantial amounts of use glyphosate for a long time
Under, the farmland of multiple countries and regions is found that 28 kinds of resistance glyphosate weeds, the weeds such as particularly common lamb's-quarters and amaranth are fast
Fast resistance rapid development.China also occurs in that many weeds resistant to glyphosate performance, ivy glorybind such as in the wheatland of North China,
The dominant weeds such as field bindweed, wartwort, Conyza canadensis of Ningbo of Zhejiang etc., field thistle in orchard, meadow pine, lettuce pod dish etc. are perennial miscellaneous
Grass, all no longer sensitive to glyphosate.
Secondly, there are significant changes in weed community.Weeds are under the selection pressure of glyphosate although weeds are to glyphosate
Resistance constantly develops, but because different weeds have difference to glyphosate-tolerant, therefore weed population transition specific resistivity bion
Frequently become apparent from.As continuous application glyphosate more than 3 years, in sweet potato field, Conyza canadensis, thorn lettuce, summer cypress, Siberian cocklebur amaranth, lamb's-quarters,
Salsola collina etc. is increased, and in cotton field Soybean Field, annual grassy weeds becomes for amaranth, dayflower, knotweed, sweet potato, green bristlegrass, piemarker and nutgrass flatsedge etc.
Main weeds.
3rd, controlling weeds unit dose increases.Glyphosate biologically active is high, and consumption is low, and price and unit area use
Low cost, is one of advantage of its sales promotion and use.Dosage under normal circumstances, orchard, plantation spray active ingredient 50
～100 grams/acre, farmland sprays 20～80 grams/acre of active ingredient, forestry, road, garden or wasteland spray active ingredient 75～
200 grams/acre, add water 15～40 liters, 200～300 times of sprayings of dilution.But in recent years, with the frequent use of glyphosate, cause miscellaneous
Grass increases to the patience of glyphosate, and present dosage reaches original 3～8 times, even more than more than the 8 of normal usage times, dilute
Release multiple and be reduced to less than 100 times.Taking 41% glyphosate isopropylamine salt water solution as a example, 150～300 milliliters of every mu of consumption originally,
200～900 milliliters of every mu of consumption now.
In addition, in production application, due to glyphosate, under conventional formulation rate, herbicidal effect reduces, in order to improve grass
The herbicidal effect of sweet phosphine, user arbitrarily with other herbicides or non-farm chemical ingredients mixture, arbitrarily increase consumption, change user
Method etc., lead to crop occur poisoning, person poultry poisoning, pollution environment, effect difference the problems such as often occur.
