Abstract
The invention relates to control of an agriculture insect, and especially relates to new purposes of methomyl for control of athetis lepigone. By using the methomyl to control athetis lepigone, the dosage of the methomyl is low. Under routine dosage of the methomyl, control effect of fourth instar larvae is over 80% indoors, which is equal to the effect of other medicaments such as phoxim and chlopyrifos. The control effect of the methomyl is over 90% in the field. Because the methomyl does not belong to organophosphorus, the methomyl is relatively safe in use.
Description
Technical field
The present invention relates to a kind of agricultural insect management, particularly relate to a kind of new purposes of utilizing 2 committees of Methomyl control noctuid.
Background technology
2 the committee noctuid [
Athetis lepigone(M schler, 1860)] be the de novo a kind of pest in China summer corn producing region.
According to the interrelated data record, domestic early than find 2 committee's noctuid harm summer corn seedlings in July, 2005 in the area, Shijiazhuang City, Hebei Province, larva is bored the moth basal part of stem, it is dead to cause the withered heart of seedling to be wilted, or bites corn root broken, causes lodging, cause the serious disconnected ridge that is short of seedling, this belongs to reported first at home.It is reported, 2 committee noctuids were generally taken place in summer corn district, the middle and south, Hebei province in 2010,2011 in Hebei, province such as Henan, Shandong, Shanxi, Anhui, Jiangsu break out, the generation area reaches more than 3,000 ten thousand mu, the minority plot is reseeded or is ruined kind, is rare serious insect pest in the Maize Production in recent years.
It is reported that 2 committee noctuid adults are liked covering the activity of moist place and laying eggs, larva is also liked covering the movable and damage to crops seedling in moist place.1 female worm can lay eggs 300 ~ 500, and what have around the one strain maize seedling of field reaches 20 larvas.In recent years, the extra large summer corn of the Yellow River and Huai He River producing region had realized generally that wheat mechanized harvest, summer corn pasted stubble sowing etc., and the harvested stalk of wheat directly is scattering into the field, and endangering for breaking out of 2 committee noctuids provides large tracts of land favourable suitable environment.
For generation and the harm of controlling this insect, producing at present and being applied to prevent and treat two medicaments of selecting committee's exigua larvae mainly is organophosphorous pesticides such as phoxim, chlopyrifos, carry out the spraying control of full field, or perfusion prevents and treats.The noctuid occurrence scope is wide because 2 are entrusted on the one hand, field worm amount is big, and dosage is many and greatly, long-term application easily makes insect develop immunity to drugs; On the other hand, the noctuid control of 2 committees is to the 8-9 leaf phase behind the corn seeding, particularly the 3-7 leaf phase is the control key period, this in period corn field generally generally use weed killer herbicide, wherein the nicosulfuron herbicide agent is use always a kind of, if use organophosphorous pesticide and nicosulfuron, be easy to generate poisoning in seven days.For this reason, being badly in need of the agricultural chemicals of new chemical safely and effectively that a kind of consumption is few, preventive effect is high at present is used alternatingly or substitutes.
Summary of the invention
The objective of the invention is at the chemical control medication when the first two some committee exigua larvae, exist dosage big, be easy to generate pesticide resistance, and organophosphorous pesticide and corn field herbicide used problems such as being easy to generate poisoning in 7 days, a kind of new purposes of utilizing 2 committees of Methomyl control noctuids is provided.
In new purposes of the present invention, the Methomyl of use is 20% methomyl milk oil.
In new purposes of the present invention, can use that Methomyl is sprayed, medicament irritates root and use, or make poison bait and use.
In spraying or irritate root when using, its working concentration is 500-800 times of liquid, preferred 500 times of liquid, mu soup 45kg.
When poison bait was used, its mu consumption was the 125-175 milliliter, preferred 175 milliliters.
In addition, also can use 90% Methomyl soluble powder, 24% Methomyl soluble liquid or 40% methomyl milk oil to replace 20% methomyl milk oil
Preferably, Methomyl can also be used for 2 committees of control noctuid with other insecticide combination back, and other insecticide is emamectin-benzoate or beta-cypermethrin.
When Methomyl and emamectin-benzoate combination, the weight ratio of the two is 16.67 ~ 37.5:1, preferred 16.67:1.
When Methomyl and beta-cypermethrin combination, the weight ratio of the two is 2.47 ~ 5.56:1, preferred 5.56:1.
Above-mentioned weight ratio is the active ingredient weight ratio.
The invention has the beneficial effects as follows: use 2 committees of Methomyl control noctuids, dosage is low, under the conventional amount used, indoor to the four-age larva control efficiency more than 80%, can reach more than 90% at field efficacy, and Methomyl do not belong to organophosphorous pesticide, use safer.
Embodiment
In order to make those skilled in the art person understand the present invention better, and above-mentioned purpose of the present invention, feature and advantage can be become apparent more, the present invention is further detailed explanation below in conjunction with embodiment,
Embodiment 1:
For examination worm source: 2 committee's exigua larvaes that the field collects in July, 2010, carry out artificial feeding indoor, obtain adult and with lay eggs and raise to testing the required length of time.
Test method is as follows:
Stomach toxicity toxicity test method: adopt leaf dipping method to carry out the stomach toxicity toxicity test.The three-coloured amaranth blade soaked 10 ~ 15s in soup after, taking-up is dried, and is that the card punch of 1cm is made the roundleaf sheet, put into 12 orifice plates with diameter, healthy 2 neat ages and 4 ages 1 in 2 committee every holes of exigua larvae are chosen, 30 larvas of every processing in 3 in every hole, repeat for 3 times, handle in contrast with clear water.Place 26 ℃ of insulating boxs to raise each processing, statistics examination worm death toll behind the 24h.
The working concentration of various medicaments is the recommended density of commodity, and when composite, the final concentration of two kinds of medicaments is half of concentration when using separately.
The gained lethality is proofreaied and correct with the Abbott formula:
Result of the test
As can be seen from Table 1, in the common insecticide for examination, different medicaments are to the drug effect difference of 2 committee noctuids, the larva pesticide resistance significant difference in the different length of times.From larva stomach toxicity effect, the second instar larvae drug effect reached has chlopyrifos (94.44%), phoxim (93.33%), Methomyl (91.67%), an emamectin-benzoate (93.33%) more than 80%; And the four-age larva pesticide resistance significantly improves, wherein the drug effect of emamectin-benzoate quickly falls to 58.89%, drug effect is still having (86.67%) two kind of organophosphorous pesticide of chlopyrifos (88.89%) phoxim and a Methomyl (83.33%) more than 80%; It is all not good to the drug effect in 2 the different worm attitude of committee noctuid length of times to test used pyrethrin pesticide, but Methomyl and efficient cypermethrin compounded use can significantly improve the stomach toxicity virulence to 2 noctuids of entrusting, and can reach 94.44% to the lethality rate of 4 instar larvaes; The composite use of Methomyl and emamectin-benzoate also has good drug effect (92.22%) to 4 instar larvaes.This shows, two select the committee noctuid to the organophosphorous pesticide sensitivity, in non-organophosphorous pesticide, Methomyl is all better to the larva stomach toxicity effect in the different length of times, be the efficient medicament of control 2 committees noctuid, in addition, although pyrethrin pesticide and emamectin-benzoate are relatively poor to 2 committee's noctuid 4 instar larvae virulence, but with the composite use of Methomyl, can significantly improve drug effect.
In summary, Methomyl can be used as the agricultural chemicals of 2 committees of control noctuids, and can be used alternatingly with phoxim, chlopyrifos etc. for 2 committees of control noctuids with pyrethrin pesticide and emamectin-benzoate are composite, slows down drug-fast generation; Or the replacement organophosphorous pesticide, use the same period with weed killer herbicide, reach the double effects of weeding and insect protected.
