Abstract
A "Xinbei" emulsified oil as agricultural chemical for preventing and treating beet noctuids and other pests with agricultural chemical resistance is prepared from 50% emulsified oil of phoxin (40-60 portions), diesel oil (20-30), emulsifier (7-10), stabilizer (0.1-2), anti-freezing agent (1-5) and solvent (rest). Its advantages are high effect, low poison and low cost.
Description
The invention belongs to a kind of agricultural chemicals, relate in particular to a kind of suffering times emulsifiable concentrate pesticide that epidermis has the beet armyworm of anti-agricultural chemicals penetrability of killing, also can expand to the anti-agricultural chemicals insect that coccid, aphid, Lepidoptera, soil insect etc. have anti-agricultural chemicals penetrability based on epidermis.
Beet armyworm is the important migratory pest of China, since the mid-90, on numerous crops of the northern area of China, caused harm and increase the weight of year by year, broke out in Henan Province in 1999 and cause disaster, more than 3,000 ten thousand mu of areas take place, the crop of causing harm comprises: beans, peanut, shallot, cotton, Chinese cabbage, corn, asparagus, capsicum, wild cabbage, sponge gourd, plum beans, balsam pear, butch clover level ground, grass lawn, wherein be injured the heaviest with soybean, shallot and asparagus; The general killed strain rate of soybean is 75-100%, and hundred strain larvas are counted the 250-600 head, several 69 of the highest larva of individual plant; The killed strain rate of shallot reaches about 85%, several about 500 of hundred strain larvas; Several 300 of Chinese cabbage, wild cabbage hundred strain larvas, several 240 of peanut hundred strain larvas, several 750 of asparagus hundred strain larvas, several 470 of capsicum hundred strain larvas, blade is almost eaten up.Beet armyworm has extremely strong pesticide resistance to Multiple Pesticides, general chrysanthemum ester class, organic phosphates, carbamate chemicals for agriculture field control effect have only about 30%, therefore caused very big loss at northern autumn-havested crops, gardening plant in 1999, insect growth regulator, IGR that control efficiency is good such as stuck gram, press down import pesticide price costlinesses such as hooligan, Mi Man, a kind of import never poison eliminates missible oil (pyrroles's organic phosphor) and also has problems in price and safety.
The objective of the invention is to overcome the deficiencies in the prior art and a kind of beet armyworm pesticide resistance that can successfully overcome be provided, reach control efficiency significantly, the suffering times emulsifiable concentrate pesticide of low toxicity, control beet armyworm that price is low.
The object of the present invention is achieved like this: be made of phoxim, diesel oil, emulsifier, stabilizing agent, antifreezing agent and solvent, and process by 50% phoxim emulsifiable concentrate 40-60 part, diesel oil 20-30 part, emulsifier 7-10 part, stabilizing agent 0.1-2 part, antifreezing agent 1-5 part and solvent surplus, described umber is parts by weight, by prescription weighing medicament, add emulsification in mulser successively.Emulsifier is any in farm chemical emulgent 0201B, 0202,0203B, 0207 type.Stabilizing agent is any of triphenyl phosphate or tributyl phosphate.Antifreezing agent is any in glycerine, the ethylene glycol.Solvent is any in the benzene,toluene,xylene.Its technological process of production is as follows: phoxim, diesel oil, emulsifier and other auxiliary agent by prescription weighing medicament, are added successively and mix, and quality inspection is carried out in emulsification in mulser at last, makes finished product then.
The present invention is directed to the beet armyworm resistance mechanism, the phoxim and the diesel oil that will belong to the hypotoxicity agricultural chemicals are used with, have successfully overcome the pesticide resistance of beet armyworm.Diesel oil is strong to beet armyworm epidermis penetration, can react with pest body inner cell matter, can also form oil film on polypide, the pore of blocking insect and cause it to suffocate.Diesel oil can also remedy the weak shortcoming of phoxim penetration, and agricultural chemicals is entered in the insect bodies very soon, improves the power of knocking down to beet armyworm greatly, especially big instar larvae is had good effect.Simultaneously hot times missible oil adhesivity can make medicament not only can also have well ovum effect extremely on the pieces of an egg attached to beet armyworm preferably attached on the larva, and the lasting period can reach 5 to 7 days.Indoor and field trial demonstration reaches well-content effect.In morning beet armyworm emergence period or medication at dusk, 1000 to 1500 times of strict control medication multiples can be avoided indivedual crops such as cucumber, Kidney bean are produced poisoning.The use of can not on jowar, spraying.
Good effect of the present invention is as follows:
1, hot times missible oil is remarkable to the beet armyworm control efficiency, is better than single agent, can solve the situation of present control beet armyworm medicament scarcity, reduces the dependence to the import agricultural chemicals, reduces the cost.
2, low toxicity, the residual quantity low (in 7 days) that is used to spray and is caused can be used for the production of pollution-free vegetable and fruit.
3, effective to big instar larvae and ovum.
4, can be used for the insect that coccid etc. is difficult to prevent and treat.
37.5% hot times of emulsifiable concentrate pesticide control soybean field beet armyworm Da Qu demonstration effect is as follows:
We have carried out the Da Qu demonstration to 37.5% hot times of emulsifiable concentrate pesticide control soybean field beet armyworm effect in soybean field, Zhou Pingling village, the Xiuwu County Li Wan of Henan Province, proving ground township at the beginning of 1999 8 months, 100 mu of demonstration areas, use 1000 times of 37.5% hot times missible oil, every mu is used the 50Kg soup to carry out field spray, with 1500 times of 1500 times of 50% phoxim emulsifiable concentrates and 4.5% high chloro milk oils as the standard control medicine, the control efficiency of 1000 times of hot times missible oil in 2 days and 5 days 37.5% reaches 90.1% and 95.1% respectively after the dispenser, 50% phoxim emulsifiable concentrate is respectively 64.0% and 64.6,4.5% high chloro milk oils for 1500 times and is respectively 50.4% and 43.8% for 1500 times.The insect density in blank district has risen 7.2% and 16.4% respectively before than dispenser.Therefore, the strong beet exigua larvae of 37.5% hot times missible oil 1000 times of antagonism property of medicine has good preventive effect, and preventive effect significantly is better than the standard control medicament, also illustrates that phoxim and diesel oil carry out rationally compositely having significant synergies to preventing and treating beet armyworm simultaneously.Hot times emulsifiable concentrate pesticide can reach 95% in 2 to 5 days through Zhengzhou, Henan Province, Jiaozhuo, the field control effectiveness test He Da district demonstration of area, Shangqiu to the beet armyworm control efficiency, compared with other conventional pesticide especially, and is very outstanding to the beet armyworm striking example ability.
The invention will be further described below in conjunction with embodiment.
The special-purpose hot times missible oil of beet armyworm be by: 50% phoxim emulsifiable concentrate (commercially available), No. 0 diesel oil, emulsifier (commercially available 0201B, 0202,0203B, 0207), stabilizing agent (commercially available triphenyl phosphate or tributyl phosphate), antifreezing agent (commercially available glycerine or ethylene glycol), solvent (toluene or dimethylbenzene) scientific formula retrofit form.
500 kilograms of embodiment 1,50% phoxim emulsifiable concentrates, 250 kilograms of No. 0 diesel oil, 70 kilograms of emulsifier (0201B), 1 kilogram of tributyl phosphate, 10 kilograms of glycerine add dimethylbenzene to 1000 kilogram.Above-mentioned each composition adds successively, emulsification in mulser.And undertaken by the following technological process of production:
