Pest-combating compositions containing pest-control actives are formulated for sustained pest-combating efficacy, utilizing actives fatty acids, undecanone, and / or soy methyl ester in varying combinations. Pest-combating includes both repellency and killing of pests. In specific formulations, the pest-combating composition includes any one, two or three of the active agents soy methyl ester, fatty acid and undecanone. Fatty acids may be unmodified or may be modified by transesterification or methanolysis of the oleochemical or conversion of the fatty acids to alkyl esters. The composition may be constituted as a spray composition, lotion, paste, or other compositional form. Pests that may be usefully combated with such composition include aphids, ants, bed bugs, bees, beetles, centipedes, caterpillars, chiggers, cockroaches, crickets, cutworms, earwigs, fleas, flies, fire ants, gnats, grasshoppers, hookworms, japanese beetles, june bugs, lice, locust, maggots, mealworms, mealybugs, millipedes, mites, mosquitoes, moths, pillbugs, scorpions, silverfish, spiders, stinkbugs, termites, thrips, ticks, wasps, and white flies.

This invention relates to a kind of nitryl methylene ramification, and its preparation method and application.

The invention discloses an organic yellow peach cultivating method which comprises the steps of garden building, field planting, shaping, fertilizing, crown regulation, flower and fruit management and pest control. According to the method, a large-scale cultivating method with standard management achieved easily is adopted, common diseases such as anthracnose, the bacterial shothole disease, the bleeding disease and leaf curl and diseases caused by aphids, buscks, longicorns and dichocrocis punctiferalis occurring during yellow peach cultivation are reduced, the yield and quality of yellow peaches are improved, and further processing of yellow peach products is facilitated.

The invention provides a method for artificially feeding ladybirds and / or lacewings. The method comprises the following steps of: (1) incubating lepidoptera insect larvae after lepidoptera insect adults lay eggs, and feeding the lepidoptera insect larvae with feed; (2) feeding ladybird larvae and / or lacewing larvae by using the lepidoptera insect larvae as feed to obtain ladybird adults and / or lacewing adults, wherein the lacewings are selected from one of chrysopa septempunctata and chrysoperla nipponensis; and (3) feeding the ladybird adults and / or chrysopa septempunctata adults by using the lepidoptera insect larvae as the feed, and feeding chrysoperla nipponensis adults by using honey and beer dry yeast powder. Compared with the prior art, the method for feeding the ladybirds and the lacewings in a large scale by using the lepidoptera insect larvae as the feed replaces the conventional method for feeding the ladybirds and the lacewings which are natural enemies of aphids by using the aphids cultured by plants, and the method saves more time and labor, is simpler and more convenient and is easier to operate.

The invention relates to the field of plant protection and the insect raising technology, in particular to an orius sauteri raising method adopting drosophila carcinophila as feedstuff. The method changes the traditional method of adopting aphid or frankliniella occidentalis as feedstuff, the defect of the orius sauteri raising caused by the problems of the two kinds of feedstuff per se is changed, the characteristics of short growth period of the drosophila carcinophila and low production environment requirement are utilized, the feedstuff basis is provided for the large-scale raising of theorius sauteri, and in addition, the feeding effect is very excellent.

The present invention relates to a Lactuca sativa seed designated 41-187 RZ, which exhibits a combination of traits including resistance against downy mildew (Bremia lactucae) races Bl:1 to Bl:17, Bl:21, Bl:23 and Ca-I to Ca-VI, currant-lettuce aphid (Nasonovia ribisnigri) biotype Nr:0, lettuce mosaic virus (LMV), and corky root rot (Sphingomonas suberifaciens), as well as having a reduced wound-induced surface discoloration. The present invention also relates to a Lactuca sativa plant produced by growing the 41-187 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 41-187 RZ.

The invention relates to a sugarcane foliar fertilizer formula: the following raw materials are added into a blender according to weight percentage of 10 percent of imidacloprid of concentration of 95 percent, 75 percent of monosultap of concentration of 95 percent and 15 percent of cartap hydrochloride of concentration of 98 percent, the materials are fully blended and added with the same amount of kaolin as filling agent and humectant, the amount of which equals to 2 percent of the raw materials, and the obtained material is ground and evenly stirred; zinc sulfate, borax, manganous sulfate and ammonium molybdate are ground respectively, and are added with, according to the weight percentage, 40 percent of zinc sulfate, 20 percent of manganous sulfate, 36 percent of borax, 3.5 percent of ammonium molybdate and 0.5 percent of gibberellin as growth regulator, then all the materials are evenly blended; the blended pesticide and the blended micronutrient fertilizer are mixed by ratio of 1 to 2, thus forming the fertilizer. The fertilizer is diluted by water by 200 times and sprayed on the plant leaves of the sugarcane. One day after the fertilizer is sprayed, control efficiency of woolly aphids is over 96 percent, and three days later, the control efficiency of woolly aphid reaches 100 percent; meanwhile, the fertilizer is efficient for egg of snout moth's larva and larvae of the sugarcane to some extent, and can reduce dead hearts in fields; after the fertilizer is absorbed by the leaves, the leaves turn green, with yield improved by 15 percent and brix improved by 0.2 percent in the fields.
