Problems solved by technology

Thrips use adults and nymphs to suck the juice of young plant tissues (twigs, leaves, flowers, fruits, etc.), the damaged young leaves and shoots become hard, curl and wither, the plants grow slowly, and the internodes shorten; young fruits (such as Eggplant, cucumber, watermelon, etc.) will harden after being killed, and cause fruit drop in severe cases, seriously affecting its yield and quality

Embodiment 1

[0018] Bioassay Example 1: Indoor joint toxicity test of cyclopronil and spinosyn compound to Thrips aubergine.

[0019] 90% cyclopronil original drug and 90% spinosad original drug were used as test agents.

[0020] The test insects were adult thrips eggplants collected from the field, raised in indoor eggplant seedlings, and the first generation of 2nd instar nymphs hatched.

[0021] Prepare different ratios of medicinal solutions, and then set 6 concentration gradients for each different ratio of medicinal solutions, fill each concentration of medicinal solutions with 3 centrifuge tubes of 1.5ml (set 3 repetitions), and make a mark , pour out the medicinal solution after standing for 4 hours, dry the centrifuge tube naturally, set aside for use, and set a blank control.

[0022] Fresh cabbage leaves were washed and dried, then soaked in each treatment solution for 10s, marked, and then dried for later use, and a blank control was set.

[0023] Heat the tip of a thin nee...

Embodiment 1

[0031] Formulation Example 1: 20% Cyclofenac Spinosad water dispersible granules.

[0032] Cyclofenac 18%, spinosad 2%, wetting agent sodium lauryl sulfate 6%, dispersing agent polycarboxylate 4%, disintegrant sodium chloride 2%, binder polyethylene glycol 3%, stabilizer soluble starch 3%, the rest is carrier kaolin. Dry pulverize, granulate, dry and sieve the above formula according to the proportion to prepare 20% cyclopronil·spinosyn water dispersible granules.

[0033] This preparation example is used for preventing and treating thrips in eggplant. The test site is located in a vegetable farm in Shizhen Village, Chenjiang Town, Huizhou City, Guangdong Province, and the object of application is Eggplant Thrips. The experimental design adopts a randomized block design, and the area of ​​the plot is 100m 2 , set 4 repetitions. Investigation method: Investigate 10 eggplant seedlings in each plot, investigate all live insects of different ages on the whole plant, investig...

Abstract

The invention discloses a pesticide composition containing dicyclanil and spinosad. The pesticide composition comprises dicyclanil, spinosad and other additives, wherein the weight ratio of the dicyclanil to the spinosad is (40:1)-(1:1), and preferably (20:1)-(1:1). The dicyclanil and spinosad account for 1-80% of the total weight of the composition. Many indoor toxicity measurement and field experiments show that the pesticide composition disclosed by the invention has an obvious synergetic effect and has good effects on preventing and controlling thrips on crops.

Description

technical field [0001] The invention relates to a pesticide composition, which uses cyclopronil and spinosad as active ingredients and is used for preventing and treating thrips in crops. Background technique [0002] Dicyclanil is a pyrimidine amine insecticide, and its mechanism of action is mainly to destroy the biochemical synthesis of amino acids in insects by inhibiting dihydrofolate reductase. It has a good control effect on pests such as tobacco leafworm, cotton boll weevil, rice brown planthopper and black-tailed leafhopper on cotton, corn, rice, vegetables and other crops. [0003] Spinosad is a secondary metabolite obtained by aerobic fermentation of Saccharopolyspora spinosa in culture medium. Its main active ingredients are spinosad (Spinosad) A and spinosad (Spinosad) D. Spinosad has rapid contact and stomach toxicity to insects, and its mechanism of action is by stimulating the nervous system of insects, increasing its spontaneous activity, resulting in non-...
