After mixing, A and B have obvious synergism, and are used for preventing and treating diseases of crops such as fruit trees, flowers, rapes, vegetables and the like, inparticular to oomycete diseases.

The invention discloses a functional healthy medical fertilizer for activating plant immunization, facilitating growth, obstructing virus transmission by insects, which essentially consists of 1-18 percent of sodium alginate, 0.5-12ppm of salicylic acid, 0.5-12ppm of lactone of zinc sulfate and 1-10 percent of brassin according to quality percentage. When applied to transplanted seedlings for root soaking and leaves surface spraying, the solution of medical combination of the invention shows remarkable biological activities: (1) being able to facilitate development of a root system and inhibiting infection to the root system from soil borne diseases, (2) obstructing the virus transmission of insect vectors, being able to replace or remarkably reduce the use of chemical insecticide on the field and presenting huge economic, environmental and social benefits, (3)inhibiting the infection of the virus, (4) activating functions of an immune system of solanaceae plants, presenting curative effects for virus diseases and securing vigorous growth of plants.

The invention relates to an insecticidal composition containing pymetrozine, in particular to an insecticidal composition containing pymetrozine and bifenthrin. The insecticidal composition is mainly characterized by containing 5 to 75 percent of pymetrozine, 0.5 to 40 percent of bifenthrin and the balance of auxiliary agent and other excipient; and the insecticidal composition is prepared into wettable powder, water dispersible granules, suspending agent and emulsion. The insecticidal composition is used for preventing and controlling aphids, white flies and plant hoppers on fruit trees, cash crops and vegetables.

The invention belongs to the technical field of pesticides, and in particular relates to an acaricide composition containing spirodiclofen, which comprises a first active component spirodiclofen and a second active component ivermectin, wherein the weight percentage of the spirodiclofen to the ivermectin is between 1 to 0.01 and 1 to 10. The prior auxiliary agents and exipients are added to the acaricide composition to be prepared into wettable powder, water dispersible granules, suspending agents, emulsifiable solution, and micro emulsion for controlling pest mites on fruit trees. The acaricide composition is good to the safety of crops and has obvious synergism.

A synergistic composite insecticide for preventing and treating beet noctuid and phytophagous mite contains inrfenuron, abamectin or methylamino abamectin benzoate, assistant and excipient.

A nematode insecticidal composition. The invention relates to a nematode insecticidal composition, effective components of which contain dithiocyano-methane (A) and fluopyram (B). The mass ratio of (A) to (B) is 100:1-1:100. After complex formulation of (A) and (B), the nematode insecticidal composition has obvious synergism. The nematode insecticidal composition is used in nematode control for plants and places of fruit trees, vegetables, grain crop, oil crops, sugar crops, linen-cotton crops, gardening plants and the like.

The invention discloses a synergic pesticide integrating synthetic pyrethroid and organophosphorus, which comprises (by weight percent) 0.1-20% of tetramethrin, ethofenprox, or bifenthrin, 10-7% of organic phosphorus insecticide, and balancing adjuvant. The pesticide can be used for controlling rice borer.

A synergistic composite insecticide for preventing and treating beet noctuid and rice borer contains flufenoxuron, organophosphorus insecticides, assistant and excipient.

The invention belongs to the field of agriculture production, and provides a physcion suspension. The physcion suspension comprises, by mass, 0.5-4% of physcion, 0.2-3% of a thickener, 0.5-1.0% of an antiseptic, 5.4-21.6% of an auxiliary material, 5-10% of a dispersant, 5% of an antifreeze agent, 0.4-1.0% of an antifoaming agent and 83-54.5% of water. The invention also provides a preparation method and an application of the physcion suspension. The physcion suspension adopts water as a dispersion medium, so no inflammability or phytotoxicity problems due to organic solvents exist; and assistants select materials with environmental compatibility, for example, sodium ligninsulfonate and xanthan gum are easy-degradation and low-toxicity products. The production and use process of the suspension has no dust harms, and is safe to operators and users.

The invention discloses a pesticide composition containing pyriproxyfen and hexaflumuron, and belongs to the technical field of pesticides. Pyriproxyfen and hexaflumuron in the pesticide composition belong to insect growth regulators; and functional mechanisms of pyriproxyfen and hexaflumuron are different, and pyriproxyfen belongs to juvenile hormone analogues, which disturbs the insect hormone balance, while hexaflumuron belongs to chitin synthesis inhibitor class, which has functions of inhibiting the chitin synthetase activity and hindering a larval molting effect. According to the pesticide composition, pyriproxyfen and hexaflumuron are mixed to play an obvious synergistic interaction function on leek late eye fungus gnat 4-instar larva, thereby improving the prevention and control effect, greatly reducing the dosage in the field, effectively reducing environmental pollution and pesticide residues and reducing the cost. In addition, two single dosages have different mechanical functions, so that the overcoming of injurious insect resistance and the delaying of the injurious insect resistance are facilitated due to the mixed using of the two single dosages. The pesticide composition containing pyriproxyfen and hexaflumuron is low in toxicity, quick in response and wide in disease prevention and treatment, and has a good pesticide effect.
