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.

The invention discloses a wide box and wide belt culture method for sugarcane. Sugarcane planting furrows with the space greater than 2m are dug, the sugarcane is planted in double rows in the sugarcane planting furrows, and soil filling and covering is carried out; a season of soybean, peanut or pepper is interplanted between the sugarcane planting furrows. The sugarcane planting line distance is increased, in addition, a season of short stem crops such as the soybean, the peanut or the pepper is interplanted between the lines, through adopting such a mode, the occupied area of the sugarcane is reduced, the ventilation and light transmission conditions are improved, diseases such as leaf spot diseases and dry top rot diseases generated under the high-temperature high-humidity and concealed conditions cannot easily occur, the generating rate of pests of ceratovacuna lanigera zehntner, mealybug and the like is smaller than that of the conventional single-crop sugarcane, more than 50 percent of pesticide and disease and pest prevention and treatment cost is reduced; in addition, the short stem crops are interplanted, the farm work operation is favorably carried out, and the field management efficiency is improved; and in addition, the short stem crops such as the peanut, the soybean and the like with nitrogen fixation capability are interplanted, partial nitrogen fertilizers can be provided for the sugarcane, and meanwhile, the consumption of chemical fertilizers is reduced.

The invention relates to a pesticidal composition in the field of pesticide compounding. Active ingredients, namely a novel quinazoline pesticide of pyrifluquinazon and a diacylhydrazine pesticide, are subjected to binary mixing, and the weight percentage ratio of the two active ingredients is 1:90-90:1, preferably (5-50):(60-5); and the pesticidal composition contains 1 to 90 mass percent of active ingredients, preferably 5 to 60 percent and the balance of auxiliary elements which are allowed to be used and acceptable in pesticides, and can be prepared into missible oil, a suspending agent, wettable powder, water dispersible granules, emulsion in water, and microemulsion. After the novel quinazoline pesticide of pyrifluquinazon and the diacylhydrazine pesticide are subjected to binary mixing, the pesticidal composition has an obvious control effect on lepidoptera such as plutella xylostella, beet armyworm, prodenia litura, cotton bollworm, striped rice borer, mealybugs and the like, and sucking mouthparts pests of homoptera, such as plant hopper, aphid, mealywing, leafhopper and the like.

The invention belongs to the field of pesticides, and concretely relates to an apple aphid control composition. Effective components of the composition comprise acetamiprid and thiamethoxam. There is no conflict after acetamiprid and thiamethoxam are blended; the effective components has a very good synergistic effect in a certain extent, has a higher control efficiency than single doses, a lasting drug effect, delays the generation of the drug resistance, reduces the use frequency of pesticides, reduces the consumption of the pesticides, reduces the use cost of the pesticides, and is effective to aphids, leafhoppers, whiteflies, plant hoppers, mealybugs, chafer larvae, potato beetles, flea beetles, threadworms, ground beetles and leaf miners, has a special effect on the control of the apple aphids, has a low residual quantity, is easy to decompose after the persistent period, is environmentally-friendly, and is of great significance to increase the yield and the income of agricultural regions.

The invention relates to an efficient insecticide composition used for killing agricultural insects. The efficient insecticide composition is composed of the following components in parts by weight: 20-50 parts of cypermethrin, 30-60 parts of phoxim, 10-40 parts of cyromazine, and 20-40 parts of sulfur-fluorine oxime ether. The efficient insecticide composition has the advantages of wide insecticidal spectrum, strong killing force and no systemic action; the efficient insecticide composition is decomposed rapidly since the efficient insecticide composition is unsteady under lights in a field, so that the residual period is short, and the residual risk is low; the efficient insecticide composition has outstanding killing effects on plutella xylostellas, asparagus caterpillars, cotton bollworms, striped rice borers, mealybugs and flies which mainly include liriomyza sativae, liriomyza huidobrensis, melanagromyza sojae, liriomyza chinensis and liriomyza trifolii.

The invention relates to a pesticidal and acaricidal composition containing sufluoxime and tebufenpyrad. The active ingredients of the composition are sufluoxime and tebufenpyrad in the weight ratio of (0.1-75):(80-1), preferentially (0.1-40):(50-5). The total mass content of the two active ingredients in the preparation is 1 to 90 percent, preferentially 5 to 60 percent. After being mixed with corresponding auxiliary agent and filler, the pesticidal and acaricidal composition can be prepared into a water emulsion, a microemulsion, missible oil, a suspending agent, wettable powder and water dispersible granules. The pesticidal and acaricidal composition is used for controlling various mites, such as red spider mites, yellow spider mites, rust mites, yellow tea mites, tetranychus cinnabarinus, tetranychus urticae and the like, and various insects with sucking mouth parts, such as aphides, thrips, psylla, mealybug, aleyrodid, scale insects and the like, of various fruit trees, such as orange trees, apple trees, grape trees, tropical fruit trees, pear trees and the like, various tea trees, and various crops and vegetables, such as cotton, soybean, humulon, potato and the like.

The invention relates to an effective pesticide composition for killing agricultural pests. The composition is prepared from the following components in parts by weight: 10-30 parts of sulfoxaflor, 15-55 parts of flubendiamide, 30-70 parts of chlorpyrifos and 35-65 parts of biopesticide lepimectin. The pesticide composition has a remarkable synergizing effect, can be safely applied to cabbages, tomatoes, oranges, strawberries, grapes and other vegetables and fruits, has a relatively broad insecticidal spectrum, has a very good dispelling and killing effect on most lepidopterous and homoptera pests, such as prodenia litura, plutella xylostella, helicoverpa armigera and mealybug, and has the characteristics of low residue, short half-life period, quick decomposition, small toxicity, high safety and the like.
