preparation example Construction

[0036] 1. Preparation of suspending agent

[0037] Preparation process: According to the formula proportions of each example in the following example, firstly grind pentadophos, component B, additives and part of water in a sand mill, after the grinding is completed, the materials are pumped into a high-speed shearing machine, and then Add antifreeze agent, thickener, remaining water and defoamer to carry out high-speed shearing, and obtain the suspension of the fungicide of the present invention after the shearing is completed.

[0039] 2. Preparation of water dispersible granules

[0040] According to the formula ratio of each example in the following example, mix each component evenly, pulverize through a jet mill, stir for 30 minutes, knead, then add to a fluidized bed for granulation, dry and sieve after granulation to obtain The water-dispersible granule of the fungicide of the present invention.

Embodiment 2

[0071] Test method: Feed planthoppers with diseased plants to infect planthoppers, and the rate of infection is about 35% after testing. Potted healthy rice plants are used for inoculation.

[0072] When the seedlings grow to 1 leaf and 1 heart ~ 2 leaves and 1 heart, the inoculation identification is carried out. Each pot was covered with a transparent cover, and the top was sealed with gauze. The number of insects needed was calculated based on 5 SBPH per seedling, and the 2-3 instar SBPH were inserted (the poisoning rate was about 35%). Deworming 2 times a day, so that the tested rice seedlings were poisoned evenly. After 48 hours, the prepared chemicals of different concentrations were evenly sprayed on the test seedlings, and each treatment was repeated 4 times, and the seedlings of each treatment grew and developed disease under natural light conditions. The treatment without drug was set as the blank control in the experiment. When the incidence of the blank control ...

Abstract

The invention relates to a pesticide composition and a bactericide thereof. The pesticide composition contains Dufulin and a thiazole bactericide, wherein a weight ratio of the Dufulin to the thiazole bactericide is (50:1)~(1:60), and the thiazole bactericide is selected from zinc thiozole, thiediazole copper and saisentong. The pesticide composition accounts for 0.1-80% of the total weight of the bactericide. The pesticide composition and the bactericide have obvious synergistic effects in control of viral and fungal diseases of various crops, and have the advantages of improvement of the control effect, reduction of the use amount of pesticides, cost reduction, drug resistance delaying, and antimicrobial spectrum enlargement.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition containing toxic fluorophosphorus and thiazole fungicides and the fungicides. Background technique [0002] In the field of pesticides, compounding pesticide active ingredients with different mechanisms of action is an effective and fast way to develop new pesticide products and control resistant pests and diseases. After the active ingredients of different pesticides are compounded, they will show three types of effects: additive effect, synergistic effect and antagonistic effect. Usually, only through a large number of experiments can we know the type of action after the active ingredients of different pesticides are compounded. [0003] Hexafluorophos is a new generation of plant anti-virus product transferred by the inventor from Guizhou University (Patent No. ZL200510003041.7). In view of its novel structure, unique mechanism of action and other ...
