Precision prevention and control plan for thrips in tomato greenhouses in Yunnan

Application scenario:

Due to the annual planting in tomato greenhouses in Honghe Prefecture, the population density of thrips has reached over 20 individuals per plant. Traditional chemical pesticides (such as imidacloprid) have less than 60% efficacy, and there is a risk of exceeding pesticide residue standards (in 2023, the local sampling inspection showed an 18% exceedance rate for acetamiprid).

Product technology:

The 20% isopyrazam microemulsion utilizes nanoscale particle size control technology:

With effective ingredient particle size ≤100nm, the penetration force is enhanced by 3 times, allowing it to penetrate the waxy epidermis of thrips;

Adding a plant-derived synergist (azadirachtin extract) can inhibit the carboxylesterase activity of thrips and delay the development of resistance.

Application value:

Quick-acting breakthrough:

Two hours after application, the pests stopped feeding, and the mortality rate reached 95.2% within 48 hours (compared to 72.6% for conventional pesticides), reducing the damage of "silver spots" on tomato fruit surfaces.

Optimization of effective duration:

The microemulsion forms a slow-release film on the leaf surface, with a duration of 14 days, reducing the need for 2 applications compared to traditional emulsifiable concentrates, saving labor costs of 120 yuan per acre.

Green certification:

The product has passed the EU REACH certification, and the pass rate of pesticide residue testing for tomatoes exported to Southeast Asia has increased to 99.7%.
