Problems solved by technology

In the seedling stage of wheat, the adults and nymphs of wheat aphids are mostly concentrated on the back of the wheat, the leaf sheaths and the heart leaves. After the jointing and earing of the wheat, the adults and nymphs are mostly clustered on the stems, leaves and young ears of the host crops. , absorbing the juice makes the leaves appear yellow spots or completely withered and yellow, growth stagnation, insufficient grout filling, reduced tillers, thin grains, and in severe cases, the ears of wheat are withered and white, and cannot be fruited, which seriously affects the yield.

Embodiment 1

[0027] Example 1: 40.5% dinotefuran · fludioxonil suspension seed coating

[0028]

[0029] According to the formula requirements, use water as the medium, add the original drug, dispersant, suspending agent and antifreeze to the ingredients and mix evenly, after being pulverized by a ball mill, grind it in a sand mill to make a suspension, after inspection After passing the test, it is measured and packaged to be the finished product.

[0030] Using 2g-3g of the mixture mixed with 80g-100g of water to mix 1kg of seeds, the control effect of take-all disease 30 days after sowing is 88.67%-90.24%, the control effect of wheat yellow dwarf disease is 87.20%-90.77%, and the control effect of aphids The effect is between 92.76% and 94.45%.

Embodiment 2

[0031] Example 2: 36% dinotefuran · fludioxonil suspension seed coating

[0032]

[0033]

[0034] According to the formula requirements, use water as the medium, add the original drug, dispersant, suspending agent and antifreeze to the ingredients and mix evenly, after being pulverized by a ball mill, grind it in a sand mill to make a suspension, after inspection After passing the test, it is measured and packaged to be the finished product.

[0035] Using 3g-4g of the mixture mixed with 80g-100g of water to mix 1kg of wheat seeds, the control effect of water-take-all disease 30 days after sowing was 89.62%-92.57%, the control effect of wheat yellow dwarf disease was 89.58%-92.12%, and the control effect of aphids The control effect is between 91.07% and 93.46%.

Embodiment 3

[0036] Example 3: 40% dinotefuran · fludioxonil suspension seed coating

[0037]

[0038] According to the formula requirements, use water as the medium, add the original drug, dispersant, suspending agent and antifreeze to the ingredients and mix evenly, after being pulverized by a ball mill, grind it in a sand mill to make a suspension, after inspection After passing the test, it is measured and packaged to be the finished product.

[0039] Using 2g-3g of the mixture mixed with 80g-100g of water to mix 1kg of wheat seeds, the control effect of water-take-all disease 30 days after sowing is 88.97%-93.44%, the control effect of wheat yellow dwarf disease is 89.36%-90.64%, and the control effect of aphids The control effect is between 91.87% and 94.76%.

Abstract

The invention relates to a pesticide composition, comprising two active components of dinotefuran and fludioxonil. The composition has high efficiency and low toxicity, can be used for preventing wheat aphis, full rot and yellow dwarf, and has excellent insecticide and bactericidal activity. While decreasing usage amount, the composition can delay the production of insecticide resistance, prolongs lasting period, reduces pollutions to the environment, is safe, and has no phytotoxicity to plants.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pesticide composition using dinotefuran and fludioxonil as active ingredients. technical background [0002] Dinotefuran is a new neonicotinoid insecticide developed by Mitsui East Asia Chemical Co., Ltd. and launched in 2002. It is the only base insecticide that does not contain chlorine atoms and aromatic rings. Known as the third-generation neonicotinoid insecticide, it has the advantages of super high efficiency, broad spectrum, less dosage, low toxicity, long-lasting drug effect, no harm to crops, and safe use. The agent has the characteristics of contact killing, stomach poisoning, strong systemic absorption by roots, high quick-acting effect, long-lasting effect, and wide insecticidal spectrum. High insecticidal activity. It is mainly used to control aphids, leafhoppers, planthoppers, thrips, whiteflies and their resistant strains on wheat, cotton, fruit trees, tobacco leave...
