Abstract
The invention relates to a weeding composition of sulfometuron methyl and atrazine, belonging to the technical field of pesticides. The weeding composition is characterized by containing 1-10% of sulfometuron and 5-35% of atrazine in percent by weight. The weeding composition can be prepared into suspending agent, wettable powder and water dispersible granules in pesticide preparation. The invention improves the pesticide effect, prolongs the duration and can remove various weeds by using pesticide at a time.
Description
Technical field
The invention belongs to technical field of pesticide, specifically a kind of sulfometuronmethyl and atrazine Herbicidal combinations with synergistic effect belongs to biological technical field.
Background technology
Sulfometuronmethyl (Sulfometuron-Methyl) sulfonylurea herbicide, it is synthetic to suppress branched-chain amino acid, thereby suppresses the cell division of plant strain growth end, stops weed growth to the chlorosis necrosis.This product is a steriland herbicide before the bud, behind the bud, be applicable to that forest prevents and kill off annual and perennial grassy weed and broad leaved weed, or open up the forest isolation strip, the forest land cleaning of lumbering back, that the wasteland is cultivated is preceding, leisure uncultivated area, the wasteland weeding of roadside, road go out filling, as fescue grass, goldenrod, broomcorn millet, earth almona, johnson grass, artemisiifolia etc.
Atrazine (atrazine) is before the interior suction selectivity seedling, herbicide after seedling.Root absorption is main, and cauline leaf absorbs seldom.Kill grass effect and the same Simanex of selectivity, easily by rainwater drip washing to soil than deep layer, also effective to some dark root grass, but easily produce poisoning.Lasting period is also longer.Be applicable to that corn, Chinese sorghum, sugarcane, fruit tree, nursery, forest land prevent and kill off lady's-grass, barnyard grass grass, green foxtail, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, some perennial weed is also had certain inhibitory action.

In order to verify whether complex preparation has synergistic effect, we adopt the check of Colby method to use the activity of back medicament to goldenrod and Eupatorium adenophorum with, grow to the 15-25 leaf in weeds and carry out during the phase, the former medicine dissolving back of sulfometuronmethyl and atrazine is become these composite and single dilution agents with 0.1% Tween 80 the soup of finite concentration gradient.Adopt the Potter spray tower to processings of spraying of weeds cauline leaf, each handles four repetitions, and each repeats to be sprayed to blade surface by medicament moistening even (the about 30s of spray time).Be treated to blank with the clear water that does not contain medicament.Adopt absolute value investigation method investigation records activity of weeding weeds fresh weight after 21 days, calculate the fresh weight preventive effect that each is handled, calculate E
0And E, work as E
0-E＞5% is synergistic effect; Work as E
0-E＜-5% is an antagonism; As-5%＜E
0One E＜5% is addition.
The activity of weeding of table 1 sulfometuronmethyl and the different composite proportionings of atrazine
The different proportionings with atrazine of table 2 sulfometuronmethyl are to the co-toxicity effect of green foxtail
The different proportionings with atrazine of table 3 sulfometuronmethyl are to the co-toxicity effect of Eupatorium adenophorum
Data in above table can obviously find out when sulfometuronmethyl and atrazine are composite, in various degree addition and synergistic effect are arranged all.Wherein the proportioning of sulfometuronmethyl and atrazine is 1: 5 o'clock, and synergistic effect is the most obvious.
Be the further checking practical effect after composite, carried out the field trial of control oranges and tangerines garden weeds in July, 2007 in Yichang, Sichuan, the single-dose agent of choosing in the test is 38% atrazine and 10% sulfometuronmethyl, proportioning in during compound drug is made a living and surveyed 4,60d observes the strain preventive effect of each medicament behind the medicine.Entire test does not have bad weathers such as rainfall, strong wind.
The test of pesticide effectiveness of table 4 sulfometuronmethyl and the different proportionings of atrazine
From above-mentioned data as can be seen, the effect that the preventive effect of sulfometuronmethyl and atrazine complex preparation control grassy weed lady's-grass, eleusine indica and broad leaved weed Horseweed Herb and composite family weeds Eupatorium adenophorum etc. all is higher than single agent far away when using.Behind the medicine during 60d to the preventive effect of Eupatorium adenophorum, lady's-grass, eleusine indica, Horseweed Herb etc. more than 95%, and the strain preventive effect less than 50% of all the other two kinds of single-dose agent, the difference performance between each is handled is extremely remarkable.And from data as can be seen, 60d behind the medicine, sulfometuronmethyl and atrazine complex preparation can keep good control efficiency, and the preventive effect of all the other single-dose agent has obviously begun to descend.Therefore, sulfometuronmethyl and atrazine complex preparation have not only improved drug effect, and prolonged the lasting period, all there have been significant raising quick-acting and lasting period that this complex preparation is described than single agent, use this complex preparation, can reduce the use cost of peasant household greatly, have the effect that a drug solves the multiple weeds in citrus garden.
