Ground maggot is a general term for the anthracidae larvae, also known as root maggot, that harm crops and vegetables underground. Once the occurrence of maggots, the root rot and crop death in the field will be mild, and the yield decrease will be serious threat to the growth of crops and farmers’ income. However, chemical pesticides used a lot, but “eggs” can not be prevented! The cost of pesticides is increasing year by year, and the resistance of maggots is becoming more and more serious, which is more difficult to control. What should farmers do?
In the process of preventing and controlling diseases and insect pests, chemical agents are indispensable
Below, take a single pyripropyl ether, chlorfenapyr, Clothianidin as an example to briefly understand the efficacy of different formulae of insecticides:
1.pyripropyl ether
Prevention and treatment of the object ：Whiteflies, insect pest shell, plutella xylostella, beet armyworm, the moth, pear yellow wood louse, thrips, etc
mechanism of action：By inhibiting the activity of insect pharyngeal lateral bodies and interfering with the biosynthesis of ecdysone, insect development metamorphosis, pupation, eclosion and adult formation can be effectively inhibited
advantage： 1. Internal inhalation, stomach toxicity, touching effect, 2. Low toxicity and long duration of safe retention 3. Strong ovicidal activity, ovicidal widely, affect larvae molting and reproduction
insufficient：It can inhibit the synthesis of chitin in the epidermal tissue of larvae and affect molting and death, but it has no effect on the death of adults and can only affect reproduction
2.chlorfenapyr
Prevention and treatment of the object ：Resistance to cotton bollworm, beet, Spodoptera, Plutella xylostella, spot miner, thrips, aphid, rapeseed and other vegetable pests: two spot nocturnal mite, grape leafchan and other pests
mechanism of action：Under the action of multifunctional oxidase, chlorfenapyr is transformed into specific insecticidal active compounds, which act on mitochondria and cause cell synthesis to cease due to lack of energy
advantage：1. Internal inhalation, stomach toxicity 2. Low toxicity, safety, long duration of efficacy 3. It has good mixing ability, good permeability and much higher activity than cypermethrin, especially in the prevention and treatment of resistant old mature larvae
insufficient：1. Do not kill eggs, 2. It is easy to occur pesticide harm, try not to use it on gourd and cruciferous vegetables
3.Clothianidin
Prevention and treatment of the object ：Hemiptera: psyllids, mealworms, cicadas, aphids, leaf-chan bugs, scale shells, etc., Coleoptera: jumping beetles, elephant turtles and other diptera: flies and mosquitoes, etc
mechanism of action：After the pest contact with the agent, it will stimulate the secretion of related enzymes in the body, leading to the excitement of the pest, and gradually paralyze and die
advantage：1. Touch and kill, internal inhalation of stomach toxicity2. Long duration of retention, low toxicity and low residue 3. Good mixing, excellent internal absorption and penetration, insecticidal broad-spectrum 4. It has certain root-raising function
insufficient：1. It is easy to be affected by temperature, and it is best to use it in ground temperature above 20 degrees Celsius 2.Should not be mixed with alkaline pesticides or substances, which will reduce the effectiveness of the drug
The above three single insecticide, pest control effect has advantages and disadvantages. Is there a compound product that has a broader insecticidal spectrum and a longer lasting effect? It can treat both eggs, larvae and adults, and has a good control effect from underground pests to pests on the ground. Do a product to prevent and control a variety of pests and diseases, use more worry? Yes it have .
28% chlorfenapyr • Clothianidin +5% pyripropyl ether
insecticidal mechanism:After coming into contact with the product, pests have strong inhibition on eggs, larvae and adults under the strong effect of internal inhalation, stomach toxicity, touching and strong ovicidal activity:
The eggs are inhibited from hatching, unable to develop into larvae, and then suffocated to death. The synthesis of molting hormone is blocked, and the larvae cannot molt and die. The adults cannot lay eggs, and when they do, the eggs they produce are inactive.
product feature：
1.Mix with sex is good, see egg kill egg, see maggot kill maggot, use two tube three generations!
2.Long duration of insecticide, broad spectrum of insecticide and egg killing, outstanding control effect
3.Regular ingredients, low toxicity and safety
4.It has certain root raising effect
