Pest repellant of the present invention can boil with the decocting of difference amount rear use, also can decoct rear concentrating, and is diluted to certain concentration during use again.Concentrate is light yellow slightly pink.

The weight ratio of capsicum annum fasciculatum and water is 1:1～1:1000 during preferred the decoction.More preferably the weight ratio of capsicum annum fasciculatum and water is 1:1～1:10.Most preferably the weight ratio of capsicum annum fasciculatum and water is 1:6.

Can improve taste when spraying for some is local, be unlikely to be pungent very much, can in the extract of capsicum annum fasciculatum, add natural perfume material, preferred rose flavored juice.

The invention also discloses the disinsection method of a kind of vegetables or fruit tree, comprising: pest repellant of the present invention is sprayed onto on vegetables or the fruit tree leaves.

Pest repellant of the present invention can be controlled the various ovum insect pests that cause because of butterfly, such as blue or green worm, caterpillar etc.Using method: on green vegetables ground and tangerine tree, when finding to have butterfly to occur, spray in advance pest repellant and can prevent effectively that butterfly from laying eggs.And in case when adult was arranged, polypide had just no longer been gnawed tender leaf after spraying, two days later from when dead.

Also can spray fruit tree, test pomegranate tree, peach, loquat, can prevent effectively that various birds from often patronizing careless unrest and pecking fruit, bird hears flavor and namely escapes.

Test pomegranate tree, gardenia, cherry-apple tree, red Japanese apricot, find also can eliminate aphis, this worm is very obstinate, though the little harm of worm is very large, the people has seen the straight thick stick of skin pimple.Close and numerous surrounding on the seedling such as fruit tree bud, beans, cotton, dish class, paddy and wheat sucked juice.The polypide color: green also has greyish brown colour band aubergine.No longer suck after spraying pest repellant of the present invention, own dead after the long period.

The below enumerates some insecticidal tests, and the pest repellant of this test usefulness namely decocts dried capsicum annum fasciculatum with 6 times of water gagings and gets, in use as required dilution:

One, kills the various ovum insect pests that cause because of butterfly

1, has a mind to attract that ovum goes out worm under the butterfly, when differently simultaneously out behind many caterpillars, we with the various dose pest repellant in different experimental field sprinklings, as with 400kg water than 1kg pest repellant, 300kg water than 1kg pest repellant, 200kg water than 1kg pest repellant, 150kg water than 1kg pest repellant.When spraying with 400kg:1kg and 300kg:1kg, what polypide had also gnaws continuing, but dead two days later.When spraying with 200kg:1kg and 150kg:1kg, weak effect is few, and polypide is not again gnawed, and all dies in two days, and what have had just die at that time.For more economical, adopt 200kg water the most suitable than 1kg pest repellant.

2, another group test is as follows:

Booth lid is raised, sprayed first pest repellant before butterfly comes, butterfly does not enter this place, several days all be the same.Butterfly has all removed not spray under the place of pest repellant ovum and has just gone out worm in a few days.Has buterfly effect so proved pest repellant.Ovum goes out worm to the vegetable grower under the butterfly as not wanting to allow, and wants again to allow the vegetable plot obtain sunlight, and that sprays pest repellant after just removing to raise the booth lid at once, sprays once after 7,8 days again, then sprays once in per 10 days, just can not go out worm.

Annotate: above test is through repeated multiple times confirmation.

Two, fruit insecticide test

300kg water, 400kg water are joined the 1kg pest repellant, and taste is strong not, and some large small bird also can patronize and jump in the tree, and some flower has also dropped, and some also will peck immature fruit.When joining the 1kg pest repellant with 200kg water, some effects have been arranged.But when joining the 1kg pest repellant with 100kg water, any bird all dare not enter the fruit tree garden.(fruit tree of last year just has fruit, such as pomegranate, loquat, green plum, has all pecked to various small birds, also special waste.So) if be used for catching up with bird, when not having aphid, on be limited to 100kg water to join the 1kg pest repellant be optimal consumption.
