Abstract
The present invention discloses a composite cartap pesticide which belongs to the technical field of composite pesticides. The composite cartap pesticide is characterized in that the pesticide comprises 0.5% to 30% of cartap and 0.02% to 2% of abamectin, or the composite cartap pesticide is characterized in that the pesticide comprises 0.5% to 30% of the cartapand 1.0% to 35% of triazophos. The composite cartap pesticide has the cotoxicity coefficient of 109.9 to 863.7, has good effects for controlling root-knot nematodes, and has the controlling rate of 95.2%. The composite cartap pesticide has fast and stable effect, small harm to environment and a human body, and low cost as 1/3 to 1/2 of the cost of products for killing the nematodes in China and foreign countries.
Description
Technical field
The invention belongs to technical field of compounded pesticide.
Background technology
Root-knot nematode is one of main disease of vegetables such as melon, Solanaceae, pulse family, celery, carrot.Abroad vegetables are produced and cause serious harm, production loss reaches 30-50%.China recent years is because the fast development that protection ground produces, and continuous cropping continuous cropping phenomenon is serious and general, makes to be becoming increasingly rampant the harm rapid spread of root-knot nematode, and production loss reaches more than 30%, and severe patient can reach the total crop failure degree.
Root-knot nematode is that a group claims that kind is a lot of, according to the various places investigation, is mainly Meloidogyne incognita, and other has javanese root knot nematode and peanut root-knot nematode.
Root-knot nematode mainly lives in the soil, and on the fibrous root and lateral root of generation and harm plant root, it is small and weak that root shows as root system, and the root amount reduces, and root system rots, and the tubbiness hyperplasia is expanded curling, forms many catenate root nodules or root knot when serious.After the morbidity of vegetables root, the institutional framework of root is destroyed, and basic function is obstructed, and directly influences the growth of overground part plant, show as a little less than the growth potential, and the blade yellow, plant is downgraded, and output reduces.Here plant withers during arid, and plant is withered when serious.
The present situation of preventing and treating, does not still have application at the present domestic starting stage that still is in of breeding for disease resistance in the production; Carry out crop rotation (comprising rice field-upland field rotation) with the crop of nematicide, it is less to protect the cultivation area, ground to carry out area at home at present.Therefore, the main method of preventing and treating is chemical control, uses nematocide.Nematocide mainly contains two types, i.e. soil fumigant and non-fumigant.
Fumigant has Celfume, ethylene dibromide, chloropicrin, dazomet etc., but since these medicaments to environment and human body harmful, condition strictness during use, price is higher, does not have and to hold effect, popularizing area is less at present.Non-fumigant is meant the furans pellet, the line spirit of going out, ethoprophos, a good year winter, iron go out gram, pass the prestige etc. of going out.Wherein majority is the high-toxic pesticide class, and country is forbidden to be used for the vegetables grown place, and some moderately toxic nematocides are arranged, and as the good year winter, but effect is not fine.Medicaments such as avermectin, Mi Leer and grain Man Ku, use cost is too high, and cost per mu reaches about 50-100 unit, and the peasant uses and also is restricted.Bacteria agent splits bright microorganism as chitin, and the load variotin is mainly the Tianwan businessman at present and promotes in China since produce effects slow, cost is high and popularizing area is less.
Summary of the invention
Based on the problems referred to above, the object of the invention is to provide that a kind of poisoning, cost are low, control root-knot nematode and soil insect is effective and quick-acting, the lasting effect technical scheme of cartap Recompounded pesticide preferably.
Described a kind of cartap Recompounded pesticide is characterized in that: contain cartap 0.5-30%, Hostathion 1.0-35%.
Described a kind of cartap Recompounded pesticide is characterized in that: the content of cartap is 1-20%, and the content of Hostathion is 1.5-15%.
Described a kind of cartap Recompounded pesticide is characterized in that: the content of cartap is 2-10%, and the content of Hostathion is 2-10%.
The chemical name of cartap is 1, and 3-two-(carbamyl sulphur)-2-dimethylamino propane hydrochloride salt is known substance, can be buied by the chemical plant, Liyang with cartap agent powder.
The chemical name of Hostathion is 0,0-diethyl-0-1-phenyl-1,2, and 4-triazole-3-base thiophosphate is known substance, can be obtained by the missible oil processing that the new agricultural chemical industry in Zhejiang joint-stock company produces.
Described cartap Recompounded pesticide is made into granule, and by a certain amount of triazophos emulsifiable solution and cartap pulvis, add adhesive and carrier again and mix stirring, after detection level is qualified, moulding, oven dry, packing.Concrete composite production technology and typical binders, assistant carrier all belong to existing known technology, do not repeat them here.Certainly, press known technology, also can make pulvis or emulsion according to the technical program.
Described cartap Recompounded pesticide, co-toxicity coefficient reaches 125.7-863.7, and the control root-knot nematode is effective, control rate reaches 92.2%, and quick-acting and lasting effect are better, and is little to the harm of environment and human body, and cost is low, only is about the 1/3-1/2 of domestic and international nematicide product.
Proportioning in the present patent application is weight content.

The grade scale that root-knot nematode is caused harm:
0 grade: no root knot;
1 grade: the little root knot of minority (accounting for below 1/3 of root system) is arranged;
3 grades: (accounting for more than 1/3 of root system) on most of root has little root knot;
5 grades: root knot is once more arranged on worm-nest;
7 grades: root knot is formed mutually and is the root knot agglomerate.
Test poisoning grade scale:
-no poisoning;
+ slight poisoning: do not influence the crop normal growth;
++ moderate poisoning: can restore, can not cause crop failure;
+++severe poisoning: influence the crop normal growth, crop yield and quality are caused to a certain degree loss;
++ ++ serious poisoning: plant growth is obstructed, and output and mass loss are serious.
Connecing the Meloidogyne incognita root nodule at the indoor pot-culture method of temperature measures, the Hostathion of low concentration (1.0%) is composite with 4.0% cartap, co-toxicity coefficient is 239.8, the Hostathion (2.0%) of middle concentration is composite with 3.0% cartap, and co-toxicity coefficient is 243.4, and the Avermectin of high concentration (3.0%) is composite with 2.0% cartap, co-toxicity coefficient is 168.2, to equivalent is that 2.5% Hostathion and 2.5% cartap are composite, and co-toxicity coefficient is 863.8, is best proportioning.
Field medicine effect test is an object with the cucumber in warm canopy, after medication 56 days, the incidence of disease of investigating Meloidogyne incognita of uprooting is 50.6%, and the root knot index is 16.9%, and control efficiency reaches 61.9%, trace it to its cause to formulation rate is not enough, in the test, every strain dosage is about 1.7g, it only is 1/3 of normal dispenser, according to our pot experiment in the greenhouse, every strain dispenser 5g, the incidence of disease is 44.4%, the root knot index is 8.9%, and control efficiency reaches 84.6%; If every strain dispenser 1.25g, the incidence of disease is 80%, and the root knot index is 16%, and control efficiency reaches 80%.
Simultaneously, in the demonstration of land for growing field crops medicament, be object with the balsam pear, every mu of medication 5kg, average every strain formulation rate is 30g, checks that the root-knot nematode incidence of disease was 6.0%, prevents that effect from reaching 92.2% in 120 days after the dispenser.
