Spirant ethyl ester is a quaternary ketoacid compound and is the best insecticide ever found with bidirectional absorption conductivity. The agent can move up and down throughout the plant to reach the foliage and bark, and this unique systemic properties protect the nascent stems, leaves and roots from the growth of eggs and larvae of pests. Another feature is the long duration of effectiveness, which can provide effective prevention and treatment for up to 8 weeks. Today, I recommend to you several excellent formulas of ethyl spirant, which control pests such as ticks and whiteflies, and the effect is very prominent.
Red wax bugs
Formula 1: 40% snail and chlorpyrifos suspension agent, in the initial incubation of mesophyllum and red wax tick eggs, with 40% spirophyllus chlorpyrifos suspension 1500-2000 times liquid spray, can quickly control the harm and spread of mesench and red wax bugs. The duration of validity can be up to 20 days. Spray only once a season.
Formula 2: 33% spirospirant thiazinone suspension, administered during the occurrence of mesozoan, can be used 33% spirothiazide 3000-3500 times liquid, evenly spray the front and back of the leaves. It has a good anti-effect on citrus tree shell insects and has a long effective period.
Formula 3: 22% spirothiasis and thiacloprid suspension agent, the formula has a good anti-effect on whitefly into nymphs, apple astragalus and pear wood lice, and has a long effective period. When controlling vegetable whitefly, the drug should be applied in the early stage of adult whitefly to the early stage of egg laying; when controlling pear tree pear lice, it should be used in the peak period of the incubation of pear tree lice eggs after the pear tree falls flowers; when controlling apple tree apple astragalus, it should be used at the beginning of apple astragalus. It can be sprayed evenly with 22% spirospirant and thiaciproline suspension 3000-5000 times liquid, which can effectively control the harm of the above pests.
Whitefly
Formula 4: 75% pyrazine · spirant ester suspension, in the early stage of egg laying of whitefly, 75% pyrazine · spirant ester suspension 8-12 grams per acre, mixed with 30 kg of water, sprayed evenly, pest contact with the agent that produces a needle blocking effect, stop feeding, lose the ability to harm to plants, and eventually starvation to death, and the process is irreversible. The two are compounded with a good synergistic effect and a long period of effectiveness.
