Embodiment 1

[0015] Example 1: Indoor Toxicity Determination of Azadirachtin, Clove Oil, Eucalyptus Oil and Their Mixtures to Cruciferous Plutella xylostella

[0016] 1. Insects to be tested: 3rd instar larvae of diamondback moth (Plutellaxylostella). Collect the mature larvae of Plutella xylostella on suburban cabbage in Nanning, Guangxi to the insect culture room, collect the formed pupae into a petri dish lined with moisturizing filter paper, and collect the pupae formed on the same day. When the hatched larvae were fed with cabbage seedlings to the third instar, the larvae with the same size were taken for testing. The breeding temperature is 25±2°C, the relative humidity is 50%-70%, and the photoperiod is 16L:8D.

[0017] 2. Test method: use dipping method. Prepare each drug solution to the required concentration, which is enough for the test. Cut fresh cabbage leaves that have not been sprayed with any chemicals and have no insect eggs into a size of 3cm×3cm, soak them in the prep...

Embodiment 2

[0023] Embodiment 2: 4.3% azadirachtin · clove oil · eucalyptus oil emulsifiable concentrate preparation

[0024] Take by weight percent azadirachtin 0.3%, eucalyptus oil 2.0%, clove oil 2.0%, sodium lauryl sulfate 2.5% (wetting agent), calcium dodecylbenzenesulfonate 2.5% (emulsifier) , N-methylpyrrolidone (co-solvent) 1.5%, ethanol 10% (solvent), xylene (solvent) to make up to 100%, each component is added to the reaction kettle in turn, and stirred evenly to make 4.3% azadirachtin ·Emulsifiable concentrate preparation of clove oil and eucalyptus oil.

[0025] This embodiment is used to prevent and control Plutella xylostella. The test site is the cabbage field in Zhenxing Village, a suburb of Nanning City. Conventional foliar spraying is used for uniform control, and the leaves are wet. The eucalyptus oil and clove oil were dissolved in ethanol to prepare 5% eucalyptus oil preparation and 5% clove preparation; 5% eucalyptus oil preparation and 5% clove oil preparation were...

Embodiment 3

[0030] Embodiment 3: 6.5% azadirachtin · clove oil · eucalyptus oil microemulsion preparation

[0031] Take by weight percent nimbin 0.5%, clove oil 4.0%, eucalyptus oil 2.0%, N-methylpyrrolidone (solvent) 2.5%, calcium dodecylbenzenesulfonate (emulsifier) ​​3.5%, three Styrylphenol polyoxyethylene oxide propylene ether (emulsifier) ​​2.5%, triphenyl phosphite (stabilizer) 3%, the above components are completely dissolved and mixed evenly, and deionized water is added to 100%. A microemulsion formulation of 6.5% azadirachtin·clove oil·eucalyptus oil was prepared under high-speed stirring.

[0032] Dissolve clove oil and eucalyptus oil with ethanol, prepare 5% clove oil preparation and 5% eucalyptus oil preparation, use the microemulsion of 6.5% azadirachtin · clove oil · eucalyptus oil as the test agent, and use 5% clove oil Oil preparations and 5% eucalyptus oil preparations were used as control agents to control cabbage armyworm, and conventional foliar sprays were used for...

Abstract

The invention relates to a plant source pesticide composition containing azadirachtin and clove oil. The plant source pesticide composition is characterized in that the azadirachtin, the clove oil and eucalyptus oil are used as active ingredients; the weight ratio of the azadirachtin, the clove oil and the eucalyptus oil in the composition is 3-7:20-50:20-50, wherein the weight percentage of the azadirachtin in the composition is 0.3 percent to 0.7 percent, the weight percentage of the clove oil in the composition is 2 percent to 5 percent, and the weight percentage of the eucalyptus oil in the composition is 2 percent to 5 percent. The plant source pesticide composition has the advantages that the active ingredients are respectively plant extracts, the toxicity to people and animals is low, the environment compatibility is good, the plant source pesticide composition is used for controlling the vegetable pests, the pesticide residues are reduced, and the health of people is favorably protected; the action mechanisms of the active ingredients are different from the action mechanisms of the chemical pesticide, the easiness in the pests generating resistance is avoided, and the effect of controlling the pests with resistance is good; the mixing of the active ingredients in certain ratio range can reach the synergistic reaction; compared with single dosage, the usage amount is less, and the medicine effect is better.

Description

technical field [0001] The invention belongs to the field of agricultural control, in particular to a pesticide synergistic composition, in particular to a botanical pesticide composition containing azadirachtin and clove oil. Background technique [0002] Insect pests are one of the main factors that affect the yield of vegetables. In order to control the threat of insect pests, people use chemical pesticides for prevention and control, but the long-term and frequent use of chemical pesticides increases the resistance of pests and reduces the control effect. Chemical pesticides are highly toxic and have a relatively long residual effect period. If the time interval from spraying to market is not enough, pesticide residues in vegetables will easily exceed the standard, which will not only pollute the environment, but also cause varying degrees of damage to human health. [0003] Although people use physical methods or biological methods to assist pest control, chemical contr...
