Chinese patent application No. 202010841880.0 discloses a seed treatment suspending agent and a preparation method and application thereof, wherein a medicament with an effect of preventing grubs, phylloxera, wireworms, cutworms, aphids, plant hoppers, whiteflies, leafhoppers, cotton bollworms and other insect pests is prepared by the action of an active ingredient, a film-forming agent, a dispersing agent, a thickening agent, an antifreezing agent, an antifoaming agent, a warning color and the like in the disclosed patent, but in the disclosed patent, the used active ingredients are clothianidin and carboxin, the carboxin is easy to decompose and lose efficacy when encountering alkaline substances, and the carboxin is required to have certain inhibition on the use of saline and alkaline land or the selection of a surfactant in the specific use process.
To further optimize the applicability and efficacy of seed treatment suspension concentrates, considerable work and research is still required by researchers in this area.
Disclosure of Invention
In order to solve the technical problems, the first aspect of the invention provides a bactericidal and insecticidal composition, which is prepared from the following raw materials: fludioxonil, chlorantraniliprole and clothianidin.
In some preferred embodiments, the mass fraction ratio of fludioxonil, chlorantraniliprole and clothianidin is (0.1-10): (0.1-10): (1-100).
In some preferred embodiments, the mass fraction ratio of fludioxonil, chlorantraniliprole and clothianidin is (0.1-1): (0.1-1): (1-10).
Further preferably, the mass fraction ratio of fludioxonil, chlorantraniliprole and clothianidin is 0.5:0.5:7.
in the experimental process, the applicant discovers through a large number of creative experiments that the dosage of the active ingredients can be greatly reduced through the interaction among fludioxonil, chlorantraniliprole and clothianidin, and the control effect on peanut grubs and peanut root rot is improved on the premise of reducing the active ingredients. Fludioxonil is used as a novel bactericide, the sterilization mechanism of the fludioxonil mainly inhibits the transfer related to glucose phosphorylation of thalli and inhibits the growth of fungal mycelia, but the cost of the active ingredient is relatively high, the amount of the active ingredient required to be added when the fludioxonil is used alone is large, the cost is increased, and the active ingredient does not meet the requirements of energy conservation and environmental protection, and the mass fraction ratio of the fludioxonil, chlorantraniliprole and clothianidin is (0.1-1): (0.1-1): (1-10), particularly, when the mass fraction ratio of fludioxonil, chlorantraniliprole and clothianidin is 0.5:0.5: and 7 hours later, the control effect of more than 80 percent is achieved 10 days after the root rot of the peanuts of the Baisha 1016 variety is leveled. The applicant speculates that the main reason is because: the clothianidin can be absorbed by plants, the clothianidin can cooperate with chlorantraniliprole when the plants have root rot germs for a certain time, the plant can stimulate the inhibition of the plants on the germs and promote the growth of peanut root systems, so that the peanuts are stronger, the risk of resisting the germs is promoted, and the effect of preventing and treating the root rot is achieved from different dimensions on the premise that the growth of real silk mycelia is inhibited by fludioxonil.
In a second aspect of the invention there is provided a seed treatment suspension comprising a germicidal insecticidal composition as described herein.
In some preferred embodiments, the preparation raw materials comprise, in weight percent: 1-15% of bactericidal and insecticidal composition, 1-5% of dispersant, 1-6% of emulsifier, 0.05-1% of thickener, 2-10% of suspension stabilizer, 1-5% of antifreeze, 0.001-0.005% of preservative, 0-5% of assistant and the balance of water to 100%.
In some preferred embodiments, the dispersant is at least one selected from the group consisting of polycarboxylate dispersants, polyoxyethylene ether dispersants, organophosphate dispersants, and formaldehyde condensate dispersants.
In some preferred embodiments, the emulsifier comprises a sodium succinate material and a phosphate material.
In some preferred embodiments, the weight ratio of the sodium succinate salt material to the phosphate ester material is 1: (0.1-2).
Further preferably, the weight ratio of the succinic acid sodium salt substance to the phosphate ester substance is 1:1.
further preferably, the sodium succinate salt substance comprises at least one of dioctyl sodium sulfosuccinate, sodium alkylphenol ether sulfosuccinate and sodium fatty alcohol succinate.
Further preferably, the sodium succinate salt material comprises dioctyl sodium sulfosuccinate.
In some preferred embodiments, the phosphate ester-based substance includes at least one of alkylphenol ethoxylate phosphate, alkyl phosphate, alkylolamide phosphate, and octylphenol ethoxylate phosphate.
Further preferably, the phosphate ester substances comprise phenol ether phosphate TXP-10.
Phenol ether phosphate TXP-10, available from Haian petrochemical plants, jiangsu province.
In some preferred embodiments, the weight ratio of sodium dioctyl sulfosuccinate to phenol ether phosphate TXP-10 is from 1:1.
the applicant finds that the addition of an emulsifier of dioctyl sodium sulfosuccinate and phenol ether phosphate ester TXP-10 to the system can greatly improve the stability of the system, particularly when the weight ratio of dioctyl sodium sulfosuccinate to phenol ether phosphate ester TXP-10 is 1:1, the reduction of the dosage of the emulsifier can be ensured, the emulsification effect under the using conditions of fludioxonil, chlorantraniliprole and clothianidin can be increased, and the reason why the phenomenon occurs is presumed to be that: with the addition of dioctyl sodium sulfosuccinate and phenol ether phosphate TXP-10 into the system, oily substances formed by active ingredients in the system can be dissolved in micelles formed by dioctyl sodium sulfosuccinate, and the synergistic phenol ether phosphate TXP-10 provides synergistic emulsified micelles in the system, so that the compatibilization of the active ingredients in the system is improved, and a foundation is laid for the effective performance and the stability of the system.
In some preferred embodiments, the thickener comprises xanthan gum and acrylic acid-acrylate copolymers.
Further preferably, the particle size of the xanthan gum is 10-500 meshes; more preferably, the particle size of the xanthan gum is 80 meshes.
Xanthan gum, model G915017, was purchased from Michelin reagent official gay.
During the experimental process, the applicant found that the control of the particle size of xanthan gum has a certain influence on the compatibility of the system and the efficacy of the active ingredient, and the reason for this phenomenon is that: in the system, with the addition of the xanthan gum, a double-helix long-chain structure existing in the xanthan gum can form a further synergistic effect with the dispersing agent and the active ingredients between the emulsifier and the acrylic acid-acrylate copolymer in the system, and the xanthan gum has a proper particle size, so that dispersed particles can be isolated in the system, and the phenomenon of precipitation or coagulation caused by collision among the dispersed particles is avoided.
Meanwhile, the applicant finds that in the system, due to the existence of the acrylic acid-acrylate copolymer, when the particle size of the added xanthan gum is too large, coagulation of the particle size is caused, and the dispersed particles in the carrying system disturb the stability of the system; however, when the added xanthan gum has a smaller particle size, the xanthan gum has a larger specific surface area and a higher surface energy, so that the collision frequency among particles is increased, the stability of the system is also influenced, and the stability of the xanthan gum during long-term storage is improved.
In some preferred embodiments, the suspension stabilizer comprises magnesium aluminum silicate.
In some preferred embodiments, the auxiliary agent comprises a colorant, an acrylic acid-acrylic acid ester copolymer.
In some preferred embodiments, the colorant is a heshuhong colorant.

4.3 method of calculating drug efficacy
The emergence rate and the control effect are calculated according to the formulas (1), (2), (3) and (4):
in the formula:
CK 1 -post-drug disease index of the clear water control zone;
PT 1 -post-drug disease index in the drug treatment area.
4.4 direct effects on crops
And (4) observing whether the pesticide has phytotoxicity on crops during pesticide effect investigation. The phytotoxicity degree of each cell is recorded according to the phytotoxicity grading method and is represented by-, + + + + and+ + +.
The phytotoxicity grading method comprises the following steps:
-: no chemical injury;
+: mild phytotoxicity, no influence on the normal growth of crops;
++: moderate phytotoxicity, can be recovered, and can not cause crop yield reduction;
+++: severe phytotoxicity affects the normal growth of crops and causes certain loss on the yield and quality of the crops;
++++: severe phytotoxicity, hindered crop growth, severe crop yield and quality loss.
5) Test results and analysis
Test data statistical analysis of the control efficacy of each treatment was performed using the duncan's new range of repolarization (DMRT) using DPS (v 9.05) software.
6) Analysis of test results
The seed treatment suspending agent prepared in the embodiment of the application is used for preventing and treating peanut root rot, seed coating is carried out on seeds with the preparation amount of 1000, 1500 and 2000 g/100 kg of seed medicament, and the prevention effect is respectively 64.24%, 73.50% and 80.22% in 10 days after seedling completion; the control effect 30 days after the seedlings are aligned is 60.91 percent, 70.37 percent and 77.47 percent respectively; the control effect 60 days after the seedlings are aligned is 49.53 percent, 62.75 percent and 70.06 percent respectively. The control substance 25 g/L fludioxonil suspension seed coating agent preparation amount is 600 g/100 kg of seeds, and the control effect 10 days after seedling completion is 83.86%; the control effect 30 days after the seedlings are aligned is 80.08 percent; the control effect 60 days after aligning seedlings is 71.73 percent.
The seed treatment suspending agent prepared in the embodiment of the application has positive correlation between the control effect on the flower root rot and the preparation amount, and the control effect difference of the low, medium and high dosage treatment of the tested substance is obvious. Compared with the control substance of 25 g/L fludioxonil suspension seed coating preparation amount of 600 g/100 kg of seeds, the control effect of the low and medium dose treatment of the test substance is obviously lower than the control effect of the test substance, and the control effect of the high dose treatment is not obviously different from the control effect of the high dose treatment.
The field observation shows that the emergence rate of the peanuts treated by the test substances has no significant difference with the control substance treatment and the clear water control treatment, the peanuts grow normally, and no phytotoxicity symptom is observed; the tested substance has certain effect of treating peanut aphids and grubs; no effect of the test substance on other non-target organisms was found at the test dose.
