Abstract

The invention discloses a cotton bollworm pesticide. The cotton bollworm pesticide is mainly prepared from, by weight, 1 part of emamectin benzoate, 1 to 5 parts of phoxim, 2 to 8 parts of tannic acid, 2 to 6 parts of malathion, 1 to 7 parts of indoxacarb, 15 to 20 parts of aconitine, 20 to 30 parts of herba ephedra, and 0.1 to 0.5 part of sodium carboxymethylcellulose. Compared with the prior art, the cotton bollworm pesticide is excellent in drug effect, and long in effect persistent period, is capable of reducing using times, saving raw materials, and reducing environmental pollution.

Description

One grows cotton cotton bollworm agent for killing

Technical field

The present invention relates to a kind of Pest killing agent, be specifically related to a kind of cotton bollworm agent for killing being exclusively used in cotton.

Background technology

Cotton bollworm, becomes long 15 ~ 20 millimeters of polypide, wing expanse 27 ~ 38 millimeters.Female moth fore wing russet or yellowish-brown, male moth mostly is celadon or cinerous, kidney shape line and circular whorl crineous, and the secondary color of outer horizontal line and sub-outer horizontal line is darker.The yellowish grey of hind wing, nearly peripheral edge portion dark brown, outer rim inside middle portion has canescence crescent spot.Yolk white, hemispherical, 0.5 mm in size, main loose product, in cotton stem or branch top vane front, also has on bud sepal surface.Larva is totally 6 ages.Body long age 4.5 ~ 6 in age 2 ~ 3, two, three ages 35 ~ 37 millimeters age 33 ~ 36, six age 15 ~ 24, five in age 9 ~ 12, four.Each body segment generally has workprint 12, and after four ages, there are many thin longitudinal grins the body back of the body and side.Body colour alters a great deal, and has green, yellowish green, reddish brown, yellowish-brown isochrome.The long 17-20 millimeter of pupal cell.Belly the 5th, six saves each joint leading edge and to gather ring-type punctum, and the back side is closeer than the outside of belly.Tail end has 1 pair of cremaster.Cotton bollworm is the major pest of cotton cotton buds and bolls phase, and be extensively distributed in China and all over the world, Chinese cotton region and vegetables flake all have generation.Cotton region, the Huanghe valley, cotton region, the Yangtze river basin are injured heavier, and therefore, the control of cotton bollworm is most important for Cotton Industry.

At present, the pesticide control of cotton bollworm is of a great variety, mostly needs repeatedly to use, not only loaded down with trivial details, and repeatedly uses increase environmental pollution, and effect is undesirable.

Experimental example gained agent for killing of the present invention is to the killing test of cotton cotton bollworm

There is early stage cotton bollworm, from cotton field, gather cotton bollworm, under Artificial feeding conditions, carry out sterilize experiment.Cotton bollworm 250, is divided into 5 groups at random, be respectively contrast 1 group, contrast 2 groups, embodiment 3 groups, embodiment 4 groups and embodiment 5 groups;

Contrast 1 group and use the pungent missible oil of 20% fluorine bell, use 1 time;

Contrast 2 groups and use the pungent missible oil of 20% fluorine bell, use 2 times, after using 2 days for the first time, use 1 time again;

Embodiment 3 groups, embodiment 4 groups and embodiment 5 groups, use the embodiment of the present invention 3, embodiment 4 and embodiment 5 gained agent for killing respectively, only use 1 time, and consumption is with contrast 1 group and contrast 2 groups.

After 5 days and 7 days, observe death condition after the medicine of each group of cotton bollworm;

Lethality after medicine: refer to after drug administration after certain hour, death toll accounts for the percentage of total test number.

Table 1 respectively organizes agent for killing to the killing effect of cotton cotton bollworm

Note: compared with contrast 1 group, * P<0.05; Compared with contrast 2 groups, #P<0.05.

As seen from the above table, compared with contrast 1 group, namely with only use compared with the pungent missible oil of 20% fluorine bell, gained agent for killing of the present invention is used once, and after medicine, the lethality of 5 days and 7 days is significantly increased, and show that agent for killing drug effect of the present invention is given prominence to, the lasting period is long.

Compared with contrast 2 groups, namely with use compared with twice pungent missible oil of 20% fluorine bell, gained agent for killing of the present invention, suitable with it to the killing effect of cotton cotton bollworm.Therefore, cotton bollworm agent for killing of the present invention is only used once, can reach the effect that the pungent missible oil of 20% fluorine bell uses twice.So agent for killing of the present invention can reduce the access times of medicine, economizes in raw materials, and environmental pollution can be reduced.
